Upgrading the Switch Software Table 2 Supported Operating Systems and Browsers Operating System Minimum Service Pack or Patch Microsoft Internet Explorer1 Netscape Navigator Windows 2000 None 5.5 or 6.0 7.1 Windows XP None 5.5 or 6.0 7.1 1. Service Pack 1 or higher is required for Internet Explorer 5.5. Cluster Compatibility You cannot create and manage switch clusters through the device manager. To create and manage switch clusters, use the command-line interface (CLI).
PAGE 4
Upgrading the Switch Software Deciding Which Files to Use The upgrade procedures in these release notes describe how to perform the upgrade by using a tar file. This file contains the Cisco IOS image file and the files needed for the embedded device manager. You must use the tar file to upgrade the switch through the device manager. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.
PAGE 5
Installation Notes For more information about assigning an IP address and default gateway to the switch, refer to the software configuration guide for this release. Step 9 Download the image file from the TFTP server to the switch. If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command: archive download-sw /overwrite /reload tftp:[[//location]/directory]/image-name.

Major Features Major Features This release contains no new features. Minimum Cisco IOS Release for Major Features Table 3 lists the minimum software release required to support the major features on this switch. Table 3 CGESM Switch Features and the Minimum Cisco IOS Release Required Feature Minimum Cisco IOS Release Required Support for DSCP transparency 12.2(25)SE1 Support for VLAN-based QoS and hierarchical policy maps on SVIs 12.2(25)SE1 Device manager 12.2(25)SE1 Support for SSL version 3.

Limitations and Restrictions • “IP Telephony” section on page 8 • “Multicasting” section on page 9 • “QoS” section on page 9 • “SPAN and RSPAN” section on page 9 • “Trunking” section on page 10 • “VLAN” section on page 10 Configuration These are the configuration limitations: • If you run the CLI-based setup program, the IP address that the Dynamic Host Configuration Protocol (DCHP) provides is reflected as a static IP address in the config.text file.
PAGE 8
Limitations and Restrictions • When connected to some third-party devices that send early preambles, a switch port operating at 100 Mbps full duplex or 100 Mbps half duplex might bounce the line protocol up and down. The problem is observed only when the switch is receiving frames. The workaround is to configure the port for 10 Mbps and half duplex or to connect a hub or a nonaffected device to the switch.
PAGE 9
Limitations and Restrictions Multicasting These are the multicasting limitations: • If the number of multicast routes and Internet Group Management Protocol (IGMP) groups are more than the maximum number specified by the show sdm prefer global configuration command, the traffic received on unknown groups is flooded in the received VLAN even though the show ip igmp snooping multicast-table privileged EXEC command output shows otherwise.
PAGE 10
Limitations and Restrictions • Egress SPAN routed packets (both unicast and multicast) show the incorrect source MAC address. For remote SPAN packets, the source MAC address should be the MAC address of the egress VLAN, but instead the packet shows the MAC address of the RSPAN VLAN. For local SPAN packets with native encapsulation on the destination port, the packet shows the MAC address of VLAN 1. This problem does not appear with local SPAN when the encapsulation replicate option is used.
PAGE 11
Device Manager Notes Device Manager Limitations and Restrictions These are the device manager limitations and restrictions: • You cannot create and manage switch clusters through the device manager. To create and manage switch clusters, use the CLI. • When you are prompted to accept the security certificate and you click No, you only see a blank screen, and the device manager does not launch. The workaround is to click Yes when you are prompted to accept the certificate.
PAGE 12
VLAN Interfaces and MAC Addresses Command Purpose Step 3 end Return to privileged EXEC mode. Step 4 show running-config Verify your entries. • The device manager uses the HTTP protocol (the default is port 80) and the default method of authentication (the enable password) to communicate with the switch through any of its Ethernet ports and to allow switch management from a standard web browser.
PAGE 13
Documentation Notes By default, VLAN 1 is the interface that connects to the management network. When the switch boots up, the DHCP client (switch) requests an IP address from a DHCP server by using the MAC address of VLAN 1. Documentation Notes This section describes documentation notes related to this IOS release. References to IOS Release Number These documents refer to Release 12.2(25)SE. The correct release is Release 12.2(25)SE1.

Open Caveats If the service config command does not find the configuration files, these error messages appear: %Error %Error %Error %Error opening opening opening opening tftp://255.255.255.255/network-confg (Timed out) tftp://255.255.255.255/cisconet.cfg (Timed out) tftp://255.255.255.255/router-confg (Timed out) tftp://255.255.255.255/ciscortr.cfg (Timed out) These system messages also appear: 00:01:40: %SYS-4-CONFIG_RESOLVE_FAILURE: System config parse from (tftp://255.255.255.
PAGE 15
Open Caveats • CSCsd85770 When you apply the mls qos trust dscp global configuration command to a port, this error message might appear.
PAGE 16
Resolved Caveats Open HP Caveats These are the HP severity 2 open caveats for this release: • rQm 263546 Disconnecting the cable from the console port does not end a Telnet session. If you are in privileged EXEC mode when you remove the cable, the next session that is started on the console port will also be in privileged EXEC mode. The workaround is to end the session before you remove the cable. • rQm 266129 If you power on a switch that does not have a config.
PAGE 17
Resolved Caveats The United States Computer Emergency Response Team (US-CERT) has assigned Vulnerability Note VU#878044 to these vulnerabilities. Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-0960 has been assigned to these vulnerabilities. This advisory will be posted at http://www.cisco.com/warp/public/707/cisco-sa-20080610-snmpv3.
PAGE 18
Resolved Caveats • CSCsd51530 When you telnet to a switch and enter the autocommand-options nohangup interface configuration command on VTY lines 0 through 4, you can now successfully log out and telnet back into the switch. In previous releases, when you logged out of the switch and then tried to open a new Telnet session, the switch would automatically log you out. • CSCse48664 The dot1dBasePort values in the Bridge-MIB now match the front-panel numbering for the switch FastEthernet interfaces.
PAGE 19
Resolved Caveats • CSCei80087 It is no longer necessary to detach and then reapply a hierarchical policy map to force changes to a VLAN level class-map to take effect. • CSCek26492 Symptoms: A router may crash if it receives a packet with a specific crafted IP option as detailed in Cisco Security Advisory: Crafted IP Option Vulnerability: http://www.cisco.com/warp/public/707/cisco-sa-20070124-crafted-ip-option.shtml Conditions: This DDTS resolves a symptom of CSCec71950.
PAGE 20
Resolved Caveats • CSCsc84880 When the radius-server source-ports 1645-1646 global configuration command is removed, the switch no longer sends the RADIUS server requests with incorrect source ports. • CSCsd16059 A switch now correctly forwards nonstandard Virtual Router Redundancy Protocol (VRRP) packets. (In nonstandard VRRP packets, the Layer 3 destination is a multicast address, but the Layer 2 destination address is a unicast address.
