convert a switchport to a L3

[gdelarosa]

Hi, I'm trying to convert a switchport into a L3 port in a 4507R running IOS Version 12.2(20)EW, but when I execute the command "no swtichport" it displays the following message: "Command rejected: Not a convertible port."

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

Sw2-L3-4507#sh run in gig4/10

Building configuration...

Current configuration : 87 bytes

!

interface GigabitEthernet4/10

switchport access vlan 2

spanning-tree portfast

end

Sw2-L3-4507#

Sw2-L3-4507#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Sw2-L3-4507(config)#in gig4/10

Sw2-L3-4507(config-if)#no switchport

Command rejected: Not a convertible port.

Do have redundant Supervisors? Are you using SSO redundancy? If so, try changing it to RPR mode

I'm not using redundant Supervisors, I do have another 4507R and I'm running HSRP between both 4507's.

In the other 4507R I can convert switchports into L3 ports with no problem at all.

In other 4500 im running IOS Version 12.2(18)EW2.

Single Supervisors can have SSO configured as well. Check your configuration by doing a sh run.

Prkrishn,

Thanks for your comments.

I checked the config both 4507's the active one have:

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

!

redundancy

mode rpr

!

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

And the standby (this is the one I can't configure L3 ports) have this:

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

!

redundancy

mode sso

!

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

I don't understando what sso stands for, should I change that configuration?

Do you think that will solve my problem?

I was thinking change de IOS version to the one that is using the 4507 active.

What do you think?

SSO stands for stateful switchover.

This is a configuration which makes a difference if you have two supervisors in the chassis. Change from SSO to RPR and you should be fine.

No need to upgrade IOS just for this reason, but if you are considering, 12.2(18)EW4 should be a good release.
