NM-ESW-16 configuration

Hi all

I've been trying to configure this network module with not much luck. It is in a 2620XM and all I am trying to do is to have devices in three separate VLANs (e.g. servers) attached on the switching side and then being routed onto another subnet.

Currently my vlan output is as follows:

R0#sh vlan-switch

VLAN Name Status Ports

---- -------------------------------- --------- -------------------------------

1 default active

10 POD active Fa1/0, Fa1/1, Fa1/2, Fa1/3, Fa1/4, Fa1/5

20 SERVICE active Fa1/6, Fa1/7, Fa1/8, Fa1/9, Fa1/10

30 MISC active Fa1/11, Fa1/12, Fa1/13, Fa1/14, Fa1/15

1002 fddi-default active

A snip from the running config

!

interface FastEthernet0/0

ip address 192.168.1.2 255.255.255.224

duplex auto

speed auto

!

!

interface Vlan1

no ip address

!

interface Vlan10

ip address 192.168.1.33 255.255.255.224

!

interface Vlan20

ip address 192.168.1.65 255.255.255.224

!

interface Vlan30

ip address 192.168.1.97 255.255.255.224

!

Routing table as follows:

Gateway of last resort is not set

* 192.168.1.0/27 is subnetted, 4 subnets

C 192.168.1.96 is directly connected, Vlan30

C 192.168.1.64 is directly connected, Vlan20

C 192.168.1.32 is directly connected, Vlan10

C* 192.168.1.0 is directly connected, FastEthernet0/0

I thought that by setting up Layer 3 VLANs using SVIs, I would have at least inter-vlan communication, but I haven't :) All the ports in the module have been configured with "switchport mode access".

I'm clearly missing something, but now can't see the forest for the trees.

The first step for me would be to get the inter-vlan communication working between the networks of 192.168.1.32/27, 192.168.1.64/27, and 192.168.1.96/27 and then to allow those subnets access to the 192.168.1.0/27 subnet.

Any pointers in the right direction would be great. I'm not asking for a definitive answer, but just a prod in the general area as I'd like to figure this out.

Yeah, I've just double-checked to make sure that I can ping the gateway IP's from the relevant boxes and all is good.

I'll keep trawling the docs like the ones here <http://www.cisco.com/en/US/docs/ios/12_4/interface/configuration/guide/h1636nm.html> that are specific to the module.

When I crack it (as I am sure it is my error), I'll post back in case someone else is having the same trouble.

It's close to midnight here and I have an exam on Monday so need to stop distracting myself with this for the time being :) Thanks for all your help though!

I'm having exactly this same issue.Under a time crunch . Sorry I have no recommendations for you, but I've tried exaclty the same and am at the same place.
