• “Trunking”

• “VLAN”

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 ^^^^^^^^^^^^^^ Typos 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 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.

The workaround is to reconfigure the static IP address. (CSCea71176 and CSCdz11708)

1. Disable auto-QoS on the interface.

2. Change the routed port to a nonrouted port or the reverse.

3. Re-enable auto-QoS on the interface. (CSCec44169)

The DHCP snooping binding database is not written to flash or a remote file in either of

these situations:

— The DHCP snooping database file is manually removed from the file system. After

you enable the DHCP snooping database by configuring a database URL, a database

file is created. If you manually remove the file from the system, the DHCP snooping

database does not create another database file. You need to disable the DHCP

snooping database and enable it again to create the database file.

— The URL for the configured DHCP snooping database was replaced because the

original URL is not accessible. The new URL might not take effect after the timeout

of the old URL.

No workaround is necessary; these are the designed behaviors. (CSCed50819)
