[c-nsp] vlan problem in my router

[Deric Kwok]

Hi

I have problem to create vlan in my router 28 serise.

I can create vlan database

1/ I can't use name command as "router(vlan)# name net1"

2/ I can't config t the vlan as "(config)#vlan 10  ===> % Invalid
input detected at '^' marker."

ls my router supporting vlan?

if not, how I can create vlan as my router is only 2 ports.

Thank you
