Cisco 877 maximum VLAN & QoS Bugs???

[stevep]

Hi All,

I am currently configuring a Cisco 877 router and I believe that I have run into a software bug with the 877.

The unit shipped with IOS 124-4.T2, I was able to configure 4 additional VLANs to the default VLAN through the VLAN database as expected and everything was working fine until I tried to apply my QoS service-policy to the Dialer Interface. Unexpectedly the router suffered a software forced reload and dumped it's output to flash. When the unit came up again I tried to apply the service-policy, same story the unit crashed.

I then downloaded 124-6.T1 and proceeded to recreate my VLANS, the VLAN.dat file copied successfully back to flash but the VLANS were not visible? (yet another bug??) When trying to recreate my VLANS as I added the fifth VLAN the following error occured.

*****UKBURL877-001(vlan)#vlan 5 name Guest*****

*****Vlan can not be added. Maximum number of 4 vlan(s) in the database.*****

I have now just upgraded to 124-6.T2 (release date 18/05) and when adding in the fifth VLAN the same error as above occurs.

I didn't even bother trying to add the service-policy after the IOS upgrades as my project requires 5 VLANs in total.

Anbody else running into the same bug?????

When my Smartnet comes through i'm going to open up a TAC on this but until then I was hoping that somebody out there might have an answer. ; )

TIA

Steve.

Hi

As per CCO it does support a max no of 4 VLANs do refer this link for the same.

About the QOS policy can you paste (the relevant QOS class maps & policy map config)what you are trying to do over there ?

Hi,

The following is taken fron the Q&A with regards to the Cisco 870 series router.

Q.What does the integrated 10/100 switch provide?

A.All models have an integrated 10/100 4-port switch. Cisco 870 series provide a Managed Switch with upto four 802.1Q VLANs in addition to

a default VLAN; each switch port could be assigned to a different VLAN as desired.

The service-policy follows:

policy-map RB-SPLIT-TUNNEL

class HTTP

priority percent 50

class INTERNETWORK-CONTROL

bandwidth percent 5

class BRANCH-NET-MGMT

bandwidth percent 5

class CORPORATE

bandwidth percent 14

class P2P

drop

class SQL-SLAMMER

drop

class WORMS

drop

class SCAVENGER

bandwidth percent 1

class class-default

bandwidth percent 25

I have successfully applied this policy to a number of 837's with success, but as mentioned previous I forces the 877 into a software forced reload.

Thanks.

Hi There

I ran into a simlar issue.

You can use 4 VLAN's excluding VLAN 1 if you include VLAN 1 you can use 5 vlans.

VLAN 1 is always there and can not be removed.

Thanks
