PAGE 198
2CSPC4.XCT-SWUM2XX1.book Page 198 Monday, October 3, 2011 11:05 AM Special System Files The following special filenames are used to refer to special virtual system files, which are under control of the system and may not be removed or added. These file names are reserved and may not be used as user-defined files. When the user copies a local source file into one of these special files and the source file has an attached file description, it also is copied as the file description for the special file.

2CSPC4.XCT-SWUM2XX1.book Page 199 Monday, October 3, 2011 11:05 AM • The CLI is accessible from remote telnet through the IP address for the switch. IP addresses are assigned separately for the service port and the inband ports. • The CLI is accessible from a secure shell interface. • The CLI generates keys for SSH locally. • The serial session defaults to 9600 baud rate, eight data bits, non-parity and one stop bit.
PAGE 200
2CSPC4.XCT-SWUM2XX1.book Page 200 Monday, October 3, 2011 11:05 AM User Access Control In addition to authenticating a user, the CLI also assigns the user access to one of two security levels. Level 1 has read-only access. This level allow the user to read information but not configure the switch. The access to this level cannot be modified. Level 15 is the special access level assigned to the superuser of the switch. This level has full access to all functions within the switch and can not be modified.
PAGE 201
2CSPC4.XCT-SWUM2XX1.book Page 201 Monday, October 3, 2011 11:05 AM Syslogs The CLI uses syslog support to send logging messages to a remote syslog server. The user configures the switch to generate all logging messages to a remote log server. If no remote log server exists, then the CLI maintains a rolling log of at most the last 1000 critical system events.
PAGE 202
2CSPC4.XCT-SWUM2XX1.book Page 202 Monday, October 3, 2011 11:05 AM this case, the CLI suppresses repeated events from the same source and instead the CLI records one event within a period of time and includes that count as part of the log. Management ACL In addition to user access control, the system also manages access for in-band interfaces. The system allows individual hosts or subnets to access only specific management protocols.

In 4.x, the default enable authentication method for telnet and SSH uses the enableNetList method, which requires an enable password. If users are unable to enter privileged mode when accessing the switch via telnet or SSH, the administrator will need to either change the enable authentication method, e.g.

2CSPC4.XCT-SWUM2XX1.book Page 267 Monday, October 3, 2011 11:05 AM 5 ACL Commands Access to a switch or router can be made more secure through the use of Access Control Lists (ACLs) to control the type of traffic allowed into or out of specific ports. An ACL consists of a series of rules, each of which describes the type of traffic to be processed and the actions to take for packets that meet the classification criteria. Rules within an ACL are evaluated sequentially until a match is found, if any.
PAGE 268
2CSPC4.XCT-SWUM2XX1.book Page 268 Monday, October 3, 2011 11:05 AM classifier rule. The ACL logging feature allows these hardware hit counts to be collected on a per-rule basis and reported periodically to the network administrator using the system logging facility and an SNMP trap. The PowerConnect ACL permit/deny rule specification supports a log parameter that enables hardware hit count collection and reporting.

2CSPC4.XCT-SWUM2XX1.book Page 329 Monday, October 3, 2011 11:05 AM DHCP Layer 2 Relay Commands 9 In the majority of network configurations, DHCP clients and their associated servers do not reside on the same IP network or subnet. Therefore, some kind of third-party agent is required to transfer DHCP messages between clients and servers. Such an agent is known as a DHCP Relay agent. The DHCP Relay agent accepts DHCP requests from any routed interface, including VLANs.

IGMP/MLD Snooping Querier allows the switch to simulate an IGMP/MLD router in a Layer 2-only network, thus removing the need to have an IGMP/MLD Router to collect the multicast group membership information. The querier function simulates a small subset of the IGMP/MLD router functionality.

2CSPC4.XCT-SWUM2XX1.book Page 559 Monday, October 3, 2011 11:05 AM 25 iSCSI Optimization Commands iSCSI Optimization provides a means of performing configuration specific to storage traffic and optionally giving traffic between iSCSI initiator and target systems special Quality of Service (QoS) treatment. iSCSI Optimization is best applied to mixed-traffic networks where iSCSI packets constitutes a portion of overall traffic.
PAGE 560
2CSPC4.XCT-SWUM2XX1.book Page 560 Monday, October 3, 2011 11:05 AM In addition, if configured, the packets can be updated with IEEE 802.1p or IP-DSCP values. This is done by enabling remark. Remarking packets with priority data provides special QoS treatment as the packets continue through the network. iSCSI Optimization borrows ACL lists from the global system pool. ACL lists allocated by iSCSI Optimization reduce the total number of ACLs available for use by the network operator.

2CSPC4.XCT-SWUM2XX1.book Page 623 Monday, October 3, 2011 11:05 AM Port Channel Commands 29 Care must be taken while enabling this type of configuration. If the Partner System is not 802.3AD compliant or the Link Aggregation Control protocol is not enabled, there may be network instability. Network instability occurs when one side assumes that the members in an aggregation are one single link, while the other side is oblivious to this aggregation and continues to treat the 'members' as individual links.
PAGE 624
2CSPC4.XCT-SWUM2XX1.book Page 624 Monday, October 3, 2011 11:05 AM A LAG can be either static or dynamic not both. It cannot have some members participate in the protocol while other members not participate. Additionally, it is not possible to change a LAG from static to dynamic via the CLI. You must remove the member ports from the static LAG and then add them to the dynamic LAG. VLANs and LAGs When members are added to a LAG, they are removed from all existing VLAN membership.
PAGE 625
2CSPC4.XCT-SWUM2XX1.book Page 625 Monday, October 3, 2011 11:05 AM A LAG failure of one or more of the links does not stop traffic in any manner. Upon failure, the flows mapped to a link are dynamically reassigned to the remaining links of the LAG. Similarly when links are added to a LAG, the conversations may need to be shifted to a new link. The purpose of link aggregation is to increase bandwidth between two switches. It is achieved by aggregating multiple ports in one logical group.
PAGE 626
2CSPC4.XCT-SWUM2XX1.book Page 626 Monday, October 3, 2011 11:05 AM The hashing algorithm is configurable for each LAG. Typically, an administrator is able to choose from hash algorithms utilizing the following attributes of a packet to determine the outgoing port: • Source MAC, VLAN, EtherType, and incoming port associated with the packet. • Source IP and Source TCP/UDP fields of the packet. • Destination MAC, VLAN, EtherType, and incoming port associated with the packet.
PAGE 627
2CSPC4.XCT-SWUM2XX1.book Page 627 Monday, October 3, 2011 11:05 AM Manual Aggregation of LAGs PowerConnect switching supports the manual addition and deletion of links to aggregates. In the manual configuration of aggregates, the ports send their Actor Information (LACPDUs) to the partner system in order to find a suitable Partner to form an aggregation. When the Partner System neglects to respond using LACPDUs, the PowerConnect switching aggregates manually.

Operating at Layer 2 of the OSI model, the VLAN is a means of parsing a single network into logical user groups or organizations as if they physically resided on a dedicated LAN segment of their own. In reality, this virtually defined community may have individual members scattered across a large, extended LAN.

Additionally, protocol-based classification allows an administrator to assign nonroutable protocols, such as NetBIOS or DECnet, to larger VLANs than routable protocols like IPX or IP. This maximizes the efficiency gains that are possible with VLANs. In port-based VLAN classification, the Port VLAN Identifier (PVID) is associated with the physical ports. The VLAN ID (VID) for an untagged packet is equal to the PVID of the port.

The networks also permit unauthorized users to attempt to access the LAN through existing equipment. In such environments, the administrator may desire to restrict access to the services offered by the LAN.
PAGE 816
2CSPC4.XCT-SWUM2XX1.book Page 816 Monday, October 3, 2011 11:05 AM Whenever an operator configures a port in Dot1x authentication mode and selects the authentication method as internal, then the user credentials received from the Dot1x supplicant is validated against the IDAS by Dot1x component. The Dot1x application accesses the Dot1x user database to check whether the user credentials present in the authentication message corresponds to a valid user or not.

It also captures the behavior of BOOTP relay agents and DHCP participants can inter operate with BOOTP participants. The host RFC’s standardize the configuration parameters which can be supplied by the DHCP server to the client. After obtaining parameters via DHCP, a DHCP client should be able to exchange packets with any other host in the Internet.

2CSPC4.XCT-SWUM2XX1.book Page 921 Monday, October 3, 2011 11:05 AM 44 GMRP Commands The GARP Multicast Registration Protocol provides a mechanism that allows networking devices to dynamically register (and de-register) Group membership information with the MAC networking devices attached to the same segment, and for that information to be disseminated across all networking devices in the bridged LAN that support Extended Filtering Services.
PAGE 922
2CSPC4.XCT-SWUM2XX1.book Page 922 Monday, October 3, 2011 11:05 AM The registration and de-registration of membership results in the multicast table being updated with a new entry or the existing entry modified. This ensures that the networking device receives multicast frames from all ports but forwards them through only those ports for which GMRP has created Group registration entry (for that multicast address).

Three versions of IGMP exist. Versions one and two are widely deployed. Since IGMP is used between end systems (often desktops) and the multicast router, the version of IGMP required depends on the end-user operating system being supported.
PAGE 926
2CSPC4.XCT-SWUM2XX1.book Page 926 Monday, October 3, 2011 11:05 AM IGMPv2 introduced a Leave Group message, which is sent by a host when it leaves a multicast group for which it was the last host to send an IGMP Report message. Receipt of this message causes the Querier possibly to reduce the remaining lifetime of its state for the group, and to send a groupspecific IGMP Query message to the multicast group.

The PowerConnect switches allows the network operator to build a complete Layer 3+ configuration with advanced functionality. As the PowerConnect defaults to Layer 2 switching functionality, routing must be explicitly enabled on the PowerConnect to perform Layer 3 forwarding.
PAGE 966
2CSPC4.XCT-SWUM2XX1.book Page 966 Monday, October 3, 2011 11:05 AM The addition of a preference option has a side benefit. The preference option allows the operator to control the preference of individual static routes relative to routes learned from other sources (such as OSPF). When routes from different sources have the same preference, PowerConnect routing prefers a static route over a dynamic route.
PAGE 967
2CSPC4.XCT-SWUM2XX1.book Page 967 Monday, October 3, 2011 11:05 AM encapsulation Use the encapsulation command in Interface Configuration (VLAN) mode to configure the Link Layer encapsulation type for the packet. Routed frames are always ethernet-encapsulated when a frame is routed to a VLAN. Syntax encapsulation {ethernet | snap} • ethernet — Specifies Ethernet encapsulation. • snap — Specifies SNAP encapsulation. Default Configuration Ethernet encapsulation is the default configuration.

Must be preceded by a forward slash (/). (Range: 1-30 bits) • secondary — Indicates the IP address is a secondary address.
PAGE 969
2CSPC4.XCT-SWUM2XX1.book Page 969 Monday, October 3, 2011 11:05 AM ip mtu Use the ip mtu command in Interface Configuration mode to set the IP Maximum Transmission Unit (MTU) on a routing interface. The IP MTU is the size of the largest IP packet that can be transmitted on the interface without fragmentation. Packets forwarded in hardware ignore the IP MTU. Packets forwarded in software are dropped if they exceed the IP MTU of the outgoing interface.
PAGE 970
2CSPC4.XCT-SWUM2XX1.book Page 970 Monday, October 3, 2011 11:05 AM Example The following example defines 1480 as the MTU for VLAN 15. console(config)#interface vlan 15 console(config-if-vlan15)#ip mtu 1480 ip netdirbcast Use the ip netdirbcast command in Interface Configuration mode to enable the forwarding of network-directed broadcasts. When enabled, network directed broadcasts are forwarded. When disabled they are dropped. Use the no form of the command to disable the broadcasts.
PAGE 971
2CSPC4.XCT-SWUM2XX1.book Page 971 Monday, October 3, 2011 11:05 AM ip route Use the ip route command in Global Configuration mode to configure a static route. Use the no form of the command to delete the static route. The IP route command sets a value for the route preference. Among routes to the same destination, the route with the lowest preference value is the route entered into the forwarding database.
PAGE 972
2CSPC4.XCT-SWUM2XX1.book Page 972 Monday, October 3, 2011 11:05 AM Example The following example identifies the ip-address subnet-mask, next-hop-ip and a preference value of 200. console(config)#ip route 192.168.10.10 255.255.255.0 192.168.20.1 metric 200 ip route default Use the ip route default command in Global Configuration mode to configure the next hop address of the default route. Use the no form of the command to delete the default route.
PAGE 973
2CSPC4.XCT-SWUM2XX1.book Page 973 Monday, October 3, 2011 11:05 AM Using this command, the administrator may manually configure a single, global default gateway. The switch installs a default route for a configured default gateway with a preference of 253, making it more preferred than the default gateways learned via DHCP, but less preferred than a static default route. The preference of these routes is not configurable.
PAGE 974
2CSPC4.XCT-SWUM2XX1.book Page 974 Monday, October 3, 2011 11:05 AM Command Mode Global Configuration mode User Guidelines Lower route distance values are preferred when determining the best route.

2CSPC4.XCT-SWUM2XX1.book Page 1097 Monday, October 3, 2011 11:05 AM OSPF Commands 53 OSPF is a link-state protocol. PowerConnect OSPF supports variable-length subnet masks. PowerConnect OSPF only operates over VLAN interfaces. OSPF operates within a hierarchy. The largest entity within the hierarchy is the autonomous system (AS), a collection of networks under a common administration sharing a common routing strategy. This is sometimes called a routing domain.
PAGE 1098
2CSPC4.XCT-SWUM2XX1.book Page 1098 Monday, October 3, 2011 11:05 AM Route Preferences Normally, OSPF select routes in the following order: • Local • Static • Intra-area • Inter-area • External • RIP PowerConnect OSPF allows the administrator to change the preference for selecting intra, inter, and external routes according to the following rules: a External route preferences apply to all ospf external routes like type1, type2, nssa-type1, nssa-type2 equally.
PAGE 1099
2CSPC4.XCT-SWUM2XX1.book Page 1099 Monday, October 3, 2011 11:05 AM • Learned Dynamically: Routing protocols can learn ECMP routes. For example, if OSPF is configured on both links connecting Router A to Router B with interface addresses 10.1.1.2 and 10.1.2.2 respectively, and Router B advertises its connection to 20.0.0.0/ 8, then Router A computes an OSPF route to 20.0.0.0/8 with next hops of 10.1.1.2 and 10.1.2.2.

2CSPC4.XCT-SWUM2XX1.book Page 1202 Monday, October 3, 2011 11:05 AM User Guidelines Normally, the network type is determined from the physical IP network type. By default all Ethernet networks are OSPF-type broadcast. Similarly, tunnel interfaces default to point-to-point. When an Ethernet port is used as a single large bandwidth IP network between two routers, the network type can be point-to-point since there are only two routers.

2CSPC4.XCT-SWUM2XX1.book Page 1267 Monday, October 3, 2011 11:05 AM 58 Virtual Router Redundancy Protocol Commands An end station running IP needs to know the address of its first hop router. While some network administrators choose to install dynamic router discovery protocols such as DHCP, others prefer to statically allocate router addresses. If the router identified by such a statically allocated address goes down, the end station loses connectivity.
PAGE 1268
2CSPC4.XCT-SWUM2XX1.book Page 1268 Monday, October 3, 2011 11:05 AM RFC defines a new configuration option that allows the router to accept any packet sent to a VRRP address, regardless of whether the VRRP Master is the address owner. The Pingable VRRP Interface feature, when enabled, allows the VRRP master to respond to both fragmented and unfragmented ICMP echo requests packets destined to a VRRP address (or addresses). A virtual router in backup state discards these.
PAGE 1269
2CSPC4.XCT-SWUM2XX1.book Page 1269 Monday, October 3, 2011 11:05 AM Interface Tracking For interface tracking, VRRP is a routing event client. When a routing interface goes up or down (or routing is disabled globally, implying all routing interfaces are down), VRRP checks if the interface is tracked. If so, it adjusts the priority. Interface tracking is useful for tracking interfaces that are not configured for VRRP. Only IP interfaces are tracked.
