Restarting an Interface

To restart an interface, use the no admin-shutdownor no shut command. For example:

•To restart interface e3 on the CSS 11501 with the no admin-shutdowncommand, enter:

(config-if[e3])# no admin-shutdown

•To restart interface e3 on the CSS 11501 with the no shut command, enter:

(config-if[e3])# no admin-shutdown

Note The CSS automatically sends a gratuitous ARP for the IP interface address when you restart the interface. The gratuitous ARP informs all network nodes about ARP mapping. The CSS transmits one ARP request packet and one ARP reply packet for every gratuitous ARP invocation.
