Re: [c-nsp] Migrating multi 1Gb port-chan member ints to 10G .....possible withot having to create a new portchan?

[CiscoNSP List]

Cheers, I labbed it up om ASR1001 -> 4948now the ASR1001 had SPA1x5G, it 
had 2 working GE-Tsadded the same SFP's (Copper/GE-T), the ASR logged the 
insertion, you could vie the details of the SFPs, but we could not get them to 
link to anything (and yes, we had enabled the ports :).SFPs worked fine in 
the 4948put some single mode fibre SFP's and worked instantly.job for 
another day to figure out)any way setup a 2 port portchan, with 5 subints 
on ASR1001, vlan int on 4948, all worked as exected.big test was removal of 
the 2 member ints on ASR1001 from portchan (Would it not allow it, or allow it, 
and delete the portchan/subintsthankfully, neither...It allowed the removal 
of all member ints, and just shutdown the portchan (Keeping al subints 
conf)..re-added the links, and all workedreplicated this on the 
ASR1006/4500X, and it also did the sameso a relatively painless change,, 
and we now have 2x10Gs in the portchan.


Thanks for all the suggestions - cheers.

Copy the config off-box, trim it down to just the subinterfaces, copy
that resulting file to bootflash. Delete the members, add the new
members, and if you have to restore the subinterfaces, copy
bootflash:subints-config-bits running-config

It's not hard, you can have your ducks all ready to go, and drop it
right back in.

I dont believe that you can remove all of a portcchan's member Ints (Ive not 
tested this, but read a forum post were someone was attempting something 
similar (1G->10G), and the router threw an error when attempting to remove the 
last 1G Int (Something along the lines of "portchan cannot be without physical 
interfaces due to sub-interfaces, at least one physical interface must be in 
the portchan")...I also had a quick look at the 1x10GSPA (SPA-1X10GE-L-V2 
(XFP)), and I dont believe they are dual rate...ie dont support manual setting 
of speed/duplexWe have tested with an older lab switch (2960), manually 
setting ports to 100M (that are Gb Ints)...with 2 "100M ports" in the portchan, 
if you try to add the "1G" ports, it complains:

 %EC-5-CANNOT_BUNDLE2: Gi1/0/25 is not compatible with Gi1/0/1 and will be 
suspended (speed of Gi1/0/25 is 1000M, Gi1/0/1 is 100M)
 %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/25, changed 
state to down

Then removing the 2 x "100M" ports from portchan, the 2 x "1G" ports 
automatically came up, and stayed up, and portchan remained upIm hoping we 
see similar behavior on the ASR1K/4500X (Under maintenance window, so small 
outage is ok).

If this causes a little downtime, why not just remove all the 1GE
interfaces and add the 10GE interface(s)?

You can pre-prepare the config and just paste it in, to avoid it taking
too much time. :)

I think this is possible, but with a little bit of downtime when you change the 
new links from 1000 to ten gig.
You should be able to lab this up with 1000Mbit and 100Mbit on an old switch, 
nothing laying around?

Hi Everyone,


Ive researched this, and the info Ive read s not entirely definitive (I dont 
have an opportunity to test  the migration in a lab unfortunately_


We have an existing port-chan on an asr1006, with 4 x 1Gb portsegress from 
ASR1006 on the member ports is very balanced, but unfortunately, ingress, we 
are always seeing 2 links basically maxing out (Other end of portchan is 
4500x(VSS stack, with "primary" switch, being the one with the 2 over active 
ports.) we've resigned to the fact that we will need to go 10G to fix the 
"issue"Now the problem is that the existing portchan has 100's of 
subunterfaces, so we dont want to have to create a "new" portchan with the 2 x 
10G links, and migrate all the subinterfacesfrom what Ive read, the member 
interfaces of the etherchan need to be of the same "Speed + Duplex"some go 
even further and say the same "physical" ty;e (i.e. 1Gb SM -> 1Gb SM)but I 
have also read where people have added a 10G int to an existing portchan (That 
only has 1Gb members), and it "worked".Can anyone please confirm if this is 
possible?  i.e. set the 10G interfaces to 1000/Full, then add them to
  the existing portchan, delete the "old" 1Gb member ints, then change the 10Gb 
interfaces to auto?  I really hope there is someway that this can be achieved 
without having to migrate all the subints to a new portchanant 
suggestions/experiences are greatly appreciated.
