Re: [c-nsp] 7200 for BGP

hi R. The G2 will certainly handle it, but I would look into the reason for having 75%, that sounds really bad. For the G1 and NPE400, I'd say you definitely need more memory - 512 MB or 1G to be fine. This is what Cisco says: The amount of memory required to store BGP routes depends on many fac

p, then you will get normal LINEPROTO-5-UPDOWN and LINK-3-UPDOWN message provided you have the 'logging event link-status' command under interface config. This is specific to 6500 though, all other switch models log LINK UP/DOWN by default. -pavel skovajsa On Tue, Dec 15, 2009 at 3:00 AM, Br

Re: [c-nsp] Cisco 4948-10GE

Hi Renelson, do a show log after shutting/unshutting the ports it will most probably tell you the reason. Usual reason is UDLD, Loopguard, BPDUguard, Etherchannel misconfig etc. etc. When the port is already disabled you can see the reason why it got into that state using command 'show errdisable

Hi, yes that is right UNI ports can't talk to each other but only within one ME3400 switch. If you have more switches and want exactly the same "switchport protected" functionality on all of them, one solution is to implement PVLANs. See http://www.rfc-editor.org/internet-drafts/draft-sanjib-priv

[c-nsp] Secondary VLAN deployment on Metro ETTH

the problem might lie in having 3rd party switches placed *between* ME3400 - they have no idea about the PVLANs hence forward it according to their VLAN tables -> which are are NOT joined -> hence the traffic is flooded on them. -pavel skovajsa ___
