I'm tring to clarify my understanding of switching paths on these line cards. From one point of view, Cisco docs says that if the traffic should ingress via one port on the line card and then should egress through another port on the same line card it will never leave this line card. So it will be switched via internal bus. Right?
No, and if it says so somewhere, please point it to the doc team to fix it. Both 6704 and 6708 have two complex of Fabric ASICs. The 6708 you can see on figure 21 here: http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/prod_white_paper0900aecd80673385.html The port mappings for Fabric ASICs should be found in the hardware installation notes under the 'Switch fabric connections' in the tables for specific LC: http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/hardware/Module_Installation/Mod_Install_Guide/02ethern.html#wp1048010 Essentially, traffic from one Fabric ASIC to the ports on the other Fabric ASIC will go over the fabric itself. Only traffic belonging the the same Fabric ASIC will be switched locally if of course there's a DFC installed. -- "There's no sense in being precise when | Łukasz Bromirski you don't know what you're talking | jid:[email protected] about."
