aye. the fact theres no 'rolling upgrade' or such is quite frustrating > * They take FOREVER to boot (in the order of five minutes...) during > which time the WHOLE STACK is unresponsive. 5 minutes? what have you dont to speed it up!!? seriously I'm sure its more like 6.5 mins > * If you're really pushing the redundancy factor, they have a current > limitation of 48 port-channels per stack. ..which sort of makes sense for a 48port model where each interface on each switch goes back to same remote system/server. but I get the issue you allude to if you have eg 4 members and want members 1/3 having dual-stacks to servers/switches and members 2/4 having dual-stacks to servers/switches I find the etherchannel support to be prettypowerful though...much more wholesome on the 3750 or 2975 than the 2960s - which has poor stacking (much lower speed, only 4 members in a stack) and far less port-channel capability.. 6 channels per stack IIRC > * They're still pricey (3750Xs are better) the good/best switches to use usually are though.... beware the cheapy models alan _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
