HWIC in 2811

HWIC is layer-II device i am using in 2811 i want to convert this to layer-III so i can assign ip address on ports. no Switchport cmd is also not working. i am trying to creat vlan but could not enter in vlan database. using 12.4 advance security IOS.

I want layer-III interafce for LAN?? please advice what 2811 supports in this module?? i tried using NM2FE2W but to no avail....its not compatible i think...yellow link blinks and then goes off......

please advise...



Re: HWIC in 2811


If you want an additional ethernet module, you can use the HWIC-1FE (the min IOS required though is 12.4(11) XJ)

HWIC-16ESW is also supported on the 2811 which gives you 16 ports and can be configured for VLAN interfaces

The 2811 also supports the NM-16ESW module

Have a look at the 2800 data sheet for the supported modules for your needs

HTH, rate if it does

beside Narayn's good advice, there is no need to create use vlan database commands, just configure interface vlan X and assign the needed ports to it.

What does it mean the switchport command doesn't work? Please be more specific.

hi aziz,

Advanced security IOS i belive shudn't hinder you from entering VLAN Database.

Nevertheless, you can:

1. create a vlan using " int vlan x"

2. Assing the FE switch port using "switch port access vlan X"

3. Connect that switch port to a router

4. sh ip int brief, you can see the port is up as well the VLAN X.

IPSEC/GRE may have issue on HWIC port, as it have limited functionality.You may test it out.
