PCT5324 64bit SNMP
I found that PCT5324 doesn't have a 64bit snmp counter.It means PCT5324 doesn't support 64bit snmp. Is there any plan to add a 64bit snmp counter in a next new firmware ?
Please let me know asap.

I'm using cacti (http://www.cacti.net/) with 64-bit (HC) counters on pretty much all network devices I have, since many links on our networks have a high sustained traffic (a few hundred Mbps). Without 64-bit counters, snmp polling every 5 minutes gives wrong results because of the 32-bit counters wrapping (at about 114Mbps)... which is why I find it really strange to have a 24 Gigabit port device without 64-bit counters. Useful interface traffic polling is pretty much impossible.
Are there still no plans to add HC 64-bit counters to a future firmware upgrade? What method would be recommended to poll/graph bandwidth usage on the 5324 without them?

The other surprise I had (and that I would have prefered to live without too), was the incredibly long delay one has to wait before a machine plugged in to that switch gets pingable (we're talking at least 10s here). Once again, this is a real problem, as my servers who try to mount nfs shares right after bringing their network interface up timeout and continue booting without having the nfs share available. Argh :-(

Matthias: Your only real choice is to poll more often. Every 5 minutes gets you up to around 110mbit, and to capture full gbit speeds you need to poll the device several times per minute.
These devices are pretty much unsuitable in an environment where monitoring is required :-(

Hi,
I don't think this has anything to do with the limitation of the ASIC. In the software , running in the switch , it wouldn't be that hard to create 64 bit counters from the 32bit counters. Just poll them every 10 sec, and create the 64 bit counters. You can also do this true SNMP, but that takes way more CPU time , then it would take , when implemented onm the switch.
And i think, a Gb switch should have counter64 on boards. We bought one over here, and are pretty happy with it, but if this isn't solved, this will be the last one.

Only thing is, that someone has to implement it.

Any new info about the 64bit SNMP issue?

I think I've just hit another limitation of the Powerconnect 5324 : I can't seem to find how to change the load balancing policy for link aggregation. I've read the entire "Link Aggregation Interoperability of the Dell™ PowerConnect™ 5316M with Cisco IOS or Cisco CatOS based Switches" PDF document from Dell, which shows how to change the policy on Cisco equipments, but not Dell switches...
I own five 5324 and only one Catalyst 3750. The Cisco is MUCH more expensive, but we had to buy it because we needed some level 3 routing capabilities between VLANs... well, I've learned to love the Cisco... 64bit counters, 4 extra ports (since the SFP slots aren't shared, but only Cisco branded SFP modules work, not Dell ones!) and level 3 routing capabilities. No ssh, though. Still, I wish Dell had some switches that were at the same level of features.
