Loss of Telnet Capability - RESOLVED
by Richard J. Sears 29 Jul '04

29 Jul '04

Thanks to everyone who provided suggestions. The problem has been resolved. There was a telnet connection on vty 2 that I was unable to clear. Thanks to Laris Benkis <laris(a)tpn.cc> who reminded me of the sho tcp brief command, I was able to locate the tcb number of the established session (which was really no longer connected) and nuke it with a clear tcp tcb # command. As soon as I did that, telnet was immediately restored to the router. Thanks again for everyone's suggestions and help. ****************************************** Richard J.

I am attempting to bridge multiple ATM vc's on a single port OC12c in my Cisco 12008. The vc's are coming from VTC video equipment. Each vc is a different channel. I need to terminate it and pass over the IP's to my gigE port. Any suggestions.

COnfiguration Suggestion - Etherchannel
by Richard J. Sears 29 Jul '04

29 Jul '04

Hey Everyone, I am building out a customer that needs more than 1000Mbps of sustained bandwidth. Because of the customer equipment, etherchannel was suggested as the means to do this (it is compatible with this customers equipment). I am running a 6509 with Dual SUP720's in IOS mode only (no cat software). It was pointed out that there are really two different ways to configure the switch - I guess my question is which is the best (lowest overhead, etc)? Hopefully someone out there has been down this road before. TIA Two methods: ! interface Port-channel2 no ip address switchport switchport access vlan 10 switchport mode access ! interface GigabitEthernet7/1 no ip address switchport switchport access vlan 10 switchport mode access channel-group 2 mode on ! interface GigabitEthernet8/1 no ip address switchport switchport access vlan 10 switchport mode access channel-group 2 mode on ! interface Vlan10 description Customer_Name ip address 192.168.0.1 255.255.0.0 no ip redirects no ip unreachables !

CWDM or DWDM passive add/drop muxes
by Greg Schwimer 29 Jul '04

29 Jul '04

Does anyone have any experience with GBIC-based CWDM and/or DWDM optical add/drop muxes (OADM)? I'm presently looking at the Cisco product lines which combines GBICs with passive multiplexors and am curious as to alternative manufacturers and the experiences other might have in these types of products in a metro application. TIA, Greg
