After analysis , we found that customer has created more than 500 Static VSI on 7700 switch .


all the VP resources were utilised and there are no free resources to cater to any more VSI.


command used to check VP resources in 7703 switch.


display diagnostic resource mpls  slot 2 (run this commnad in diag mode)





1) Delete unnecaasry VSI configuration on 7703 switch.

2) Delete unnecessry vlans on trunk ports.

3) Allowing vlan on trunk ports which belong to VSI will consume AC/VP resources. so , we should delete unnecessary vlans on ports.
