Cisco 877 and Vlans :)

[GuyCisco]

Good Day Everyone

We are building a network on a budget and managed to get 3 Cisco 877 ADSL routers for 50 bucks a piece. What a bargain!

I have a little question though. 

According to the documentation on these routers they "Should Support"up to 4 VLANs. Which is fine, you can add a network on each LAN port. This way you can work around not being able to assign virtual interfaces or being able to assign ip addresses to each individual port.

All 3 of my bargain/bin Cisco 877 routers though seem to be limited to only the default + 1 additional VLAN... Bummer seems like these are meant for REALLY small SOHO networks... 

Is there a way i can work around this limitation?

Or is there a specific version of IOS i need to load to support up to 4 VLANs?

The memory on all 3 routers seems to be limited to files up to 21mb so so the highest version of IOS I have been able to go was 12.4.24 Advanced IP Services or 15.1.4 advanced security. Currently running 12.4.24 AIS.

Kind Regards

870 supports up to 4 VLANs ... if it's loaded with IOS version 12.4 (and later).
Downgrade the IOS to 12.3 and 10 VLANs are supported.

Hi 

Unfortunately it doesn't work for me. Here i have two of my routers

one i just upgraded to IOS package c870-adventerprisek9-mz.123-8.yi3.bin

Another one on  c870-advsecurityk9-mz.124-24.T1.bin

Both of these IOS versions only allow me to add 2x vlans.

Is this maybe something stuck in the NVRAM limiting my vlans?

Hello,

I think you need Advanced IP Services to run multiple VLANs...

How much memory do you have ? Post the output of 'show version'...

[GuyCisco]

 Here is my sh version if it helps.

Referring to your post here. I think you are getting 10 Vlans because you were using a different model router the Cisco 871W (MPC8272) processor (revision 0x200) with 118784K/12288K.

I cant really say for certain since all of the 800 series routers share the same feature sheet.

I've tested this router and it can support 10 VLANs if loaded with 12.3 (HERE).

You're trying to create more than 2 VLANs running 12.4.  This won't work.

[GuyCisco]

Good Evening 

I swopped to using c870-advipservicesk9-mz.123-8.YI2.bin

But it doesnt seem to support vlans at all. I have a version of 12.3-14 thats a bit older that im going to try next then move back to 12.4 and try adv ip services

Router#conf t

I will try the advanced ip services tonight and post back thanks.

Hello,

try the 'vlan database' exec command:

There should be a vlan.dat file in your flash. What do you get with the 'vlan database' exec command ?

So can you add your VLANs here ?

E.g.:

Router(vlan)#vlan 30

Yes Georg however im still limited to 2 vlans, I reinstalled the Advanced security firmware124.23 though as advanced ip services 123.8 and .14 wont even give me the command for vlan database or to add vlans.

I will keep looking for a version of advanced ip services 124 that will give me 4x vlans. there is only 2 versions of 123 available as far as i can see.
