Re: managing switch

Hi Friend,

We manage switches for making any configuration changes, for any troubleshooting purpose, to get the stats of an interface etc etc.

Vlan 1 carries VTP, CDP , Stp bpdus etc.

Re: managing switch

Hi

In addition to Ankur's post Cisco best practice says not to use vlan 1 as management or for the native vlan. As a rule you should

1) Use a different vlan for management and shutdown vlan 1 interface.

2) Allocate all unused ports to a non-routed vlan - we use vlan 998 where i work.

3) Allocate a non-routed vlan for use as the native vlan - we use vlan 999.

Vlan 1 has some specific issues with it in terms of security and hence it is recommended not to use it. VTP, CDP & PAGP will still be carried on vlan 1 even if you don't use it.

Re: managing switch

Hi ,

In addition to above posts , it is a layer 2 device then you need to specify "ip deafilt-gateway " for reachability from outisde users which are in different vlan's.

Thanks,
