x450e-24p replacing x350-24t with mirror backup not joining network

Eduardo_Mendiza — Sat, 14 Jan 2017 01:14:00 GMT

Good day everyone,

Here is the case. Yesterday a X350-24T of one of our clients started giving fan errors so while we process the RMA we deciced to replace it with a X450e-24P. What we did was blank the X450e, copy the config from the X350 and "tfpt put" that one into the default fabric X450e.

When we booted up the X450e into production we couldn't reach our default gateway.

Things to keep in mind:

* Both switches are running the same XOS vers. 15.3.5.2 patch1-10
* We used an XGM2-2sf-1 expansion module (we checked and it was compatible with the X450e) for the connection with the gateway
* The replaced switch was part of an EAPS ring

What could be the problem

- The expansion module or the transceiver? We can see that it has an active status with 10G speed (Which commands could allow us to troubleshoot this)
- Default routing related (how to check this besides using "show ip route")
- EAPS ring related (Unlikely since we cant even reach our default gateway)
- Gateway side related problem ? (Also a Extreme Switch, X650-24P)

Any help is appreciated.

Hello Eduardo,

What IP are you pinging and where are you pinging from?

Hi Patrick,

we are going with

- ping vr vr-default 10.1.171.240

- ping 10.1.171.240

from console access to the x450

do you see an fdb entries on the uplink port?

Right now I'm on my way to the client and from what I can they are rolling back to the x350 with the faulty fans.

I know it's not optimal but they decided to do the change with a small window of 30 mins at noon in the middle of a weekday with users working.

By the time I get there there is probably no way for me to test any type of live commands (since the switch is not gonna be connected to the network)

Is there anything I could check before putting the x450 again on production (config related)?

EtherMAN — Sat, 14 Jan 2017 02:19:00 GMT

I noticed you changed the tag ID of the default vlan to 350 and created another vlan with tag ID 1

You have an EAPS ring running on port 23 and 25 but you untagged your default vlan on all ports.

Is your gateway connected to port 23 or 25 and if so is it tagged on those adjacent switches or untagged....

If you run you management vlan untagged then the adjacent has to be untagged also..

I have had problems too having an untagged vlan on an EAPS trunk port. Typically all the vlans should be tagged on your EAPS primary and secondary ports.

Hey Etherman,

You gave me a good lead. I digged on the config and compared it to the original. Apparently when the config was exported and imported all the "configure vlan" lines were not accepted by the switch and we ended up with config vlan default untagged in all ports, which seems to have been the problem. I'm going to check for any other problems when we get another window.

In perspective, always double check your config even if it is being imported directly with tftp get and put.

This makes sense if you don't remove the ports from the default VLAN before pasting in the configuration. Definitely made that mistake before. 
