Hello Ullas

I was meaning

sh ip int Vlan 88

that shows the ACLS and so on

example:

sh ip int Vlan5

Vlan5 is up, line protocol is up

Internet address is 10.98.130.3/24

Broadcast address is 255.255.255.255

Address determined by non-volatile memory

MTU is 1500 bytes

Helper address is not set

Directed broadcast forwarding is disabled

Multicast reserved groups joined: 224.0.0.1 224.0.0.2 224.0.0.22 224.0.0.13

Outgoing access list is not set

Inbound access list is not set

Proxy ARP is enabled

Local Proxy ARP is disabled

Security level is default

Split horizon is enabled

ICMP redirects are never sent

ICMP unreachables are always sent

ICMP mask replies are never sent

IP fast switching is enabled

IP Flow switching is disabled

IP CEF switching is enabled

IP CEF switching turbo vector

IP Null turbo vector

Associated unicast routing topologies:

Topology "base", operation state is UP

Associated multicast routing topologies:

Topology "base", operation state is UP

IP multicast fast switching is enabled

IP multicast distributed fast switching is disabled

Hope to help
