The 6748-SFP use one Rohini for even and one Rohini for odd ports not consecutive, IIRC. This could vary by revision. I don't have one handy to check against. The Janus and SSA are for ports 1-24 and 25-48. There are four Rohini on the board, two connected to each Janus/SSA pair.
You can use 'sh int <port> cap | inc Ports" to list the ports. And 'sh asic slot <slot>" to list the asics. This is example output of a 6724 which is consecutive. #sh int Gi1/1 cap | inc Ports Ports-in-ASIC (Sub-port ASIC) : 1-24 (1-12) The first port list is the Janus and SSA. The second is the Rohini. #sh asic-version slot 1 Module in slot 1 has 3 type(s) of ASICs ASIC Name Count Version JANUS 1 (1.0) SSA 1 (9.0) ROHINI 2 (1.5) Mack -----Original Message----- From: cisco-nsp-boun...@puck.nether.net [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Benjamin Lovell Sent: Thursday, October 28, 2010 9:38 AM To: John Neiberger Cc: cisco-nsp@puck.nether.net Subject: Re: [c-nsp] Fun problem affecting only even-numbered ports Nothing that I can think of. One Super Santa Anna and Janus run ports 1-24 and another pair of them run ports 25-48. One Rohini runs each consecutive group of 12 ports. The only thing I could guess at is the path take across the switchbar fabric but I don't recall how we select FPOE right now. -Ben On Oct 27, 2010, at 12:54 PM, John Neiberger wrote: > This is a good one.
