3725 with IP Base 12.3 doesn't accept encapsulation command - URGENT

[g.quintin]

Hello,

We have replave a 3620 router by a 3725, but the configuration of the vlan doesn't work on the 3725 because it doesn't accept the encapsulation command following:

- encap dot1Q 1

- encap ISL

Here after is the Vlan configuration:

interface FastEthernet0/0

description VERS CLIENT-PACKET VLAN

no ip address

no ip redirects

no ip unreachables

no ip proxy-arp

ip accounting access-violations

duplex auto

speed auto

no cdp enable

!

interface FastEthernet0/0.2

description vers cyber express

bandwidth 64

encapsulation dot1Q 2

ip address 10.227.2.254 255.255.255.0

ip access-group 101 in

ip nat inside

!

Is there someone to help us?

Thanks.

Hi,

I believe you need to be running the IP Plus feature set to support trunking.

Hello,

I don't think that I need IP PLus feature because the "Cisco Features navigator Tool" valid that IP Base support ISL Vlan and IEEE802.1q with release 12.3.

Maybe the feature navigator is wrong with this one. Can you try a IP Plus image?

[g.quintin]

Hello,

No, i can't try IP Plus Feature because the router 3725 is in another country.

How to know which feature to install if the tool is wrong?

I tried with IP Plus in lab and do see encapsulation options

Please, Can you verify that IP Base support these options?

Thanks

Hello,

Thanks for your answer, but it was on a IP Feature:

c3725-i-mz.123-15a => "i" seems "IP" feature only.

Can you make the test with "IP Base" Feature?

Thanks,

Regards,
