for a switch the syntax would be the following
Core_1(config)#interface gigabitethernet 1/1
Core_1(config-if)#switchport encapsulation negotiate
Core_1(config-if)#switchport trunk allowed vlan add 10
Core_1 (config-if)#
so in this example you would add vlan 10 to an already
existing statment for "allowed" for the interface
but does the 4710 support this?
we have 3 existing vlans "allowed" under an interface..but we would like to
add anthoer in the Admin context so we can crete more contexts..
however i do not see this ooption
