pixfirewall(config)# int ethernet 1

pixfirewall(config-if)# int ethernet 1.100

pixfirewall(config-subif)# ip add

pixfirewall(config-subif)# ip address 193.168.1.1 255.255.255.252

pixfirewall(config-subif)# no shut

pixfirewall(config-subif)#

pixfirewall#sh int ip brief

Hi Anuj,

You would need to assign the nameif to the interface as well:

pixfirewall(config)# int ethernet 1

pixfirewall(config)# no shut

pixfirewall(config-if)# int ethernet 1.100

pixfirewall(config-subif)# ip add

pixfirewall(config-subif)# ip address 193.168.1.1 255.255.255.252

pixfirewall(config-subif)#nameif inside (just an example for name)

pixfirewall(config-subif)# no shut

Hope that helps,

Thanks,

Hi Anuj,

Try changing the firewall mode to routed mode so that you can assign ip address to the interfaces directly. I hope that is in transparent mode so it asks for the vlans to be configured for the IP assignments.

Pls check and revert back.

Please do rate if the given information helps.

To avoid the message ERROR: VLAN must be configured for interface Ethernet1.100, try to configure the vlan before:

pixfirewall(config-if)# int Ethernet1.100

pixfirewall(config-subif)# vlan 100

...

It works on GNS3, so it's easy to solve.

Hi Anuj,

The reason why you can't configure anything on the PIX is because that particular PIX has "

Failover Only-Active/Standby (FO) license", meaning you can't configure it as a standalone PIX.

This PIX needs to be part of an Active/Standby failover PIX pair, and the configuration needs to be synchronised from the Active Primary PIX to this PIX.

Hope that answers your question why it's not configurable.
