I'm trying to compare two 7600s. We're seeing an odd issue on one, but
not the other. They both have SUP720-3BXLs on them, but the Hw field
on the first one is 5.3, while the second one is 5.7. We're seeing
this issue on the router with the 5.3 version, but we're not seeing it
on the 5.7 router. This is a multicast issue that we thought we had
figured out, but then we realized that if we were right then it should
be affecting both boxes.
Any idea what the Hw field is for? Does that indicate an earlier
version of that blade?
Yes.
I have never been able to find a definitive list of the "bugs" fixed in
later minor hardware revisions. I suspect Cisco are not keen to reveal
it; it would make their sparing difficult ("You sent me an older sup, I
want a newer one").
FWIW we have Hw 4.4, 4.6, 5.2 and 5.4 in service at various places. Hw
revision does seem to correspond roughly with purchase date i.e. newer
is higher.
