8600 3.7.4 software memory requirements

[iamsantino]

Hello,

We are currently running SW ver. 3.1.6.1 on our Passport 8600 and will be upgrading to 3.7.4.0.

I've looked scanned the 3.7 and 3.7.4 release documentation and can't find the memory requirements. Does anybody know, off the top of their heads?

as it stands, we have 128M


Passport-8610:6/show/sys# perf

CpuUtil: 10%
SwitchFabricUtil: 0%
OtherSwitchFabricUtil: 0%
BufferUtil: 0%
DramSize: 128 M
DramUsed: 68 %
DramFree: 40883 K

Also, any tips for the upgrade?

Cheers!

Found the answer P-)

A minimum of 128MB are required to support the Passport 8000 Series switch software Release 3.7. An upgrade kit of 256MB is provided in the Nortel price list; this upgrade kit is not required for the 8691SF. However, because different memory sizes (for example, 256MB for the 8690SF and 8692SF; 128MB for the 8691SF) in the same chassis can cause unpredictable behaviors, Nortel Networks does not recommend nor support a mixed configuration (8690/8691/8692) in a chassis.

iamsantino - Go with 256 Meg on any Passport CPU running 3.5.x.x. code or above.

They tell you that you can get by with 128 Meg on the 8691SF, but I've seen two customer's have problems once they loaded a fairly large config on it.

Play it safe...go with 256Meg.

(and don't believe the crap about having to buy their RAM)
