Hi guys, All I can add is what I do already. * use MRTG / RRDTool to monitor links of interest and measure bandwidth utilisation. * use Epicentre to monitor / manage switch events and thresholds and use the real time monitoring to regularly sweep across switches and look for errors * use...

Just to expand, we have over 10 BD's and I'd guess at over 50 Summits globally within our company. We had a set design in place, and asked Extreme, Cisco and Cabletron to recommend suitable equipment and provide a quote. In the end, Extreme were technically superior and cheaper than any other...

We use numerous BD's, Alpines and flavours of Summits. Over the last few years, we have found the firmware to be slightly buggy, however overall stable and much cheaper than the similar Cisco product. Technically very good product, however their tech support is poor.

I have implemented Cisco Ping MIB into MRTG / RRDtool successfully, but unfortunately I am noticing that the IP SNMP process consumes a lot of memory and doesnt release the memory, even if the polling stops. The only was to clear this is to reboot the router. Has anyone had any problems with...

Could someome explain the what ICMP Port Unreachable and ICMP Redirect for host is? The explain files arent that clear. Is there any documents that explain in depth all the error messages / expert alarms? Thanks Steve

Hi, I am trying to setup start and stop triggers that a user can initiate when they think the network is running slow, and then reset so they can keep on doing this. I have created a start capture filter based on a telnet to tcp port 4747 and the RST flag set to 1 for the no connection...
