[c-nsp] Native and management VLAN confusion

Hi Steve...

Traditionally (if possible) you would have separate management VLAN's to
each site for management purposes.  The intermediary is most likely not
permitting VLAN1 and/or untagged traffic (quite common).

Hope this helps...

Hi everyone,

We have a scenario regarding VLANs in which I'm confused as to how to 
access the remote switches:


         COE
         2924 XL
         native vlan 1
           |
           |
         trunk
           |
         vlans 500, 501, 502
           |
           |
         intermediary network
         5500
         /   |    \
        /    |      \
    trunk   trunk    trunk
    /        |          \
CPE        CPE2       CPE3
2924 XL    2924XL     2924XL
vlan 500   vlan 501   vlan 502


Untagged traffic does not pass from CPE to COE through the intermediary.

I'm confused as to how I need to configure things VLAN-wise in order to 
be able to remotely manage the CPE switches from the CO, through the 
independent intermediary. The native and management VLAN is 1 on the CPE 
side.

Could someone point me in the direction on the most appropriate way to 
make the CPE gear reachable?

Thanks,

Steve
