Hello List,
sorry for the long delay but here is the solution to this riddle. It
turns out this problem was caused by a faulty supervisor engine. As
soon as we switched to another SUP720 the problems all went away.
We then ran a full diagnostic on the faulty SUP720 which lasted 5
hours and showed

No, random. Sometimes it takes hours for it to flap. Then it stays up

Just a quick warning for people trying to upgrade a Cat4500-E with
SUP6-E to 12.2(54)SG.
The release notes for Cat4500
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/release/note/OL_5184.html
state that you need a new ROMMON (12.2(44r)SG5) when installing the
new IOS on a SUP6-E.

It certainly is, I used it on an 7606/3B-XL to upgrade from SRB5 to SRB5a.
Didn't work very good but it worked.

Hi,
has anyone a working QinQ tunnel on a Cisco 4900M? I tried it in the
lab with 12.2(50)SG Enterprise Services SSH and it didn't work.
Setup like this:

sh proc cpu shows that the "Cat4k Mgmt LoPri" process is taking most
of the CPU time:
