I'm not sure if "cdp disable" will work... you might need "no cdp enable"
Cdp, vtp, dtp, I think are cisco proprietary and you might want those disabled facing the juniper. Just a quick search online , I find the following ... I'm not sure if the following info applies to the 6500 , so please verify before using ---------------------------------------------------------------------------- ---- *** cdp http://www.cisco.com/c/en/us/td/docs/ios/12_2/configfun/command/reference/ff un_r/frf015.html To enable Cisco Discovery Protocol (CDP) on an interface, use the cdp enable interface configuration command. To disable CDP on an interface, use the no form of this command. cdp enable no cdp enable ---------------------------------------------------------------------------- ---- *** vtp http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/co nfiguration/guide/book/vtp.html#wp1029449%0A This example shows how to disable VTP mode on a port: Router# config terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface gigabitethernet 3/5 Router(config-if)# no vtp Router(config-if)# end Router# ---------------------------------------------------------------------------- ---- *** dtp http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-series-swit ches/24330-185.html switch(config-if)#switchport nonegotiate !--- Set trunking mode to not send DTP negotiation packets !--- for trunks to routers. ---------------------------------------------------------------------------- ---- *** cisco loop packet --- I'm not sure about this being proprietary, I just remember seeing this often in wireshark and maybe this could result in some of the traffic you are seeing on the juniper.... https://supportforums.cisco.com/discussion/10816351/whats-loop-traffic-ether eal -Aaron _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
