Protocol-Independent Multicast (PIM), routers maintain forwarding tables that they use to forward multicast datagrams. Packets delivered to members of the multicast group are identified by a single multicast group address. Any host, regardless of whether it is a member of a group, can send to a group. However, only the members of a group receive the message. Membership in an IP multicast group is dynamic; hosts can join and leave at any time.

Chapter 6. SNMP Management The 3524 can be managed using a Simple Network Management Protocol (SNMP) compatible management station running platforms such as HP OpenView or MG Soft’s MIB Browser. 6.1 SNMP Management Operations A network management application is concerned with performance statistics gathered by the devices on the managed network, in reading and changing current configuration information, and in receiving alerts of unusual events.
6.3 Community Name and Security SNMP v.1 was not designed to be a secure protocol. There is no true password, although the string known as a community string does serve some of the same purposes. SNMP-aware devices, such as this switch, often ship with well-known community strings. For this reason, it is important that you change the default community strings before putting the switch on a network.
• • • • • • The IP group -- This group contains counters for Internet Protocol Traffic.
Chapter 7. Switching Concepts A bridge is a hardware device used to connect multiple networks into one big network. However, when a bridge receives a broadcast from one interface, it will forward the frame to all interfaces and flood the wire, easily overwhelming the network. The traditional solution to the problem of broadcast flooding is to use a router.
7.1.3 Port VLAN ID To allow untagged packets to participate in a VLAN, a Port VLAN ID (PVID) must be assigned in the relevant port(s). Each port on the switch has a default PVID of 1 (the default VLAN) and will receive both tagged and untagged frames. You may configure the PVID of any desired port (the range is 1 to 4094). For ports that have been configured to receive only tagged frames, the PVID is meaningless.
Forward Delay After a recalculation of the spanning tree, the Forward Delay parameter regulates the delay before each port begins transmitting traffic. If a port begins forwarding traffic too soon (before a new root bridge has been selected), the network can be adversely affected. The default value for Forward Delay is 15 seconds.
7.3.2 Flow Control With a link operating at a high data rate, a switch may experience occasional limitations in the buffer space used to store Ethernet frames before forwarding them. In this situation, if the sending station continues to send frames, the switch will have no option but to discard the frames. This may quickly lead to unacceptable delays in upper-level protocols. In order to avoid unnecessarily dropping frames, a switch may implement Flow Control.
Appendix A. Troubleshooting In the unlikely event your switch does not operate properly, follow the troubleshooting tips below. If you still need help, contact Asanté’s technical support. Problem Power LED is not lit. The 10/100 port Link LEDs are not lit. The GBIC Link LED is not lit. Cannot establish communication to another device (switch, router, workstation, etc.).
