Limitations and Restrictions Limitations and Restrictions You should review this section before you begin working with the switch. These are known limitations that will not be fixed, and there is not always a workaround. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software. This section contains these limitations: • "Cisco IOS Limitations" section on page 7 • "Device Manager Limitations and Restrictions" section on page 11 • "Hardware Limitations and Restrictions" section on page 11 Cisco IOS Limitations These limitations apply to CGESM switch: • "Configuration" section on page 7 • "Ethernet" section on page 8 • "HSRP" section on page 8 • "IP" section on page 9 • "IP Telephony" section on page 9 • "Multicasting" section on page 9 • "QoS" section on page 9 • "SPAN and RSPAN" section on page 10 • "Trunking" section on page 10 • "VLAN" section on page 11 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. The workaround is to not run setup if DHCP is required for your configuration. • If you start and then end the autoinstall program before the DHCP server replies, DHCP requests are ignored. The workaround is to wait until you see the IP address appear when it is provided by the DCHP server. • A static IP address might be removed when the previously acquired DHCP IP address lease expires. This problem occurs under these conditions: - When the switch is booted up without a configuration (no config.text file in flash memory). - When the switch is connected to a DHCP server that is configured to give an address to it (the dynamic IP address is assigned to VLAN 1). - When an IP address is configured on VLAN 1 before the dynamic address lease assigned to VLAN 1 expires.
