Overview
WS-X6K-S2-PFC2 • Two dual-port 1000BASE-X GBIC uplinks
• PFC2; fabric enabled, supports optional SFM2
• QoS port architecture (Rx/Tx): 1p1q4t/1p2q2t
WS-X6500-SFM2
• (Optional) SFM2
Note The Sup2 is not supported in Cisco IOS Release 12.2SRA and later releases.
Supervisor Engine 2T • Five uplink ports on Sup 2T: two 10GE and three 1GE. The two
10GE ports use x2 as transceiver and the three 1GE ports use
SFP.
• Improved Switch fabric providing 80G/slot. Santa Monica fabric
ASIC has 26 ports of 40 Gbps each, providing a total of 1040
Gbps
• Sup 2T has MSFC5 and PFC4 (EARL8).
– MSFC5 is a dual core 1.5Ghz CPU, Combined Route
Processor/Switch Processor(RP/SP)
– Single IOS image file
– Supports USB Console port
– Supports 2Gb DRAM
– Supports 4Mb NVRAM
– Supports CMP, which has its own DRAM/Bootdisk
• One compact flash slot in the front panel. There are two types of
flashes on SUP2T:
– Internal flash (named bootdisk)
– External flash (named disk0)
Note These two types of flashs support 4Gb and 8Gb memory.
• QOS settings when the uplink ports are in different mode:
– 10G only COS-Q: RX: 8q4t; TX:1p7q4t
– Mixed: COS-Q: RX: 2q4t; TX:1p3q4t
– 1GE only : DSCP-Q : RX :8q4t, TX :1p7q4t
