VLAN commands

Use VLANs to limit the broadcast domain and establish security virtual LANs. See the procedure on page 22 on creating VLANs.

•run indicates that only the currently running configuration is changed. Changes are not restored after a reset.

•nvram indicates that only the configuration stored in NVRAM is changed. Changes do not take effect until a reset.

•all indicates that both the currently running configuration and the NVRAM configuration is changed. Changes take effect immediately and are restored after a reset.

get-con-matrix

Displays the current connectivity matrix for the switch. The first column is the source port. The other columns are destinations where frames from a given source port can be forwarded. Unlearned addresses (addresses that aren’t in the switching database) are forwarded to all ports marked with a + in the source port’s row. Learned addresses are forwarded to their destinations only if the destination is marked with a + in the source port’s row. Ports don’t need to be forwarded to themselves.
