Solved: Upgrade IOS 3550 with Routes Port

davidhuynh5 · ‎01-27-2009

Anyone know how to make a port on the 3550 a routed port instead of a switchport? I need to put an ip address on the interface to communicate with my TFTP server. It does not take the "no switchport" command. I check the technotes and no mention about turning it into a routed port.

BTW, you don't necessarily need the interface to be L3. you can make it "switchport access vlan x", then create an SVI, interface vlan x and put the ip address on that interface vlan, it will work the same way as having a physical L3 port.

That is old so maybe it didn't have much functionality back then . All you have to do then is put an address on the vlan 1 SVI and give it a default gateway . If you are just tranferring it from your pc then set your pc address into the same address space make sure your tftpserver program is running and start your transfer.

conf t

no ip routing

int vlan 1

ip adresss xxx.xxx.xxx.xxx

no shut

exit

ip default-gateway xxx.xxx.xxx.xxx

address of the gateway off the subnet.

Edit - apologies i didn't read your post fully.

Have you tried enabling routing first ie.

3550(config)# ip routing

int fa0/2

no switchport

ip address ....

yes, I tried enabling ip routing, but the command did not work. Once I get the IP address on the interface, then the upgrade is easy.

What do you mean by "it did not work". When you entered that command what happened ?

What does a "sh ip route" show.

What version of IOS are you running ?

What does the interface config look like at the moment ?

I have a feeling this is not a 3550, can you send us a show version? 3550 on up are the only L3 switch that can do L3 functionality. Anything below like 29x0, 2900XL, 3500XL are strictly L2

Can you post a "show version " ?

davidhuynh5 · ‎01-28-2009

Sorry it took a while to get the information.

Attached is the show version, logging when I try to convert a switchport to a routed port, and the show tech. I have another 3550 sitting, which was loaded by cisco with a more recent image and it can do routing and will accept a the commands

without a fuss. Thanks a million.
