Today I tested a Sup2T-XL and a Sup720BXL in the lab with full bgp feeds for ipv4 and ipv6. To my understanding the hardware capacity for the FIB TCAM is the same for Sup720-BXL and Sup2T-XL. Sup2T-XL output of "sh platform hardware capacity":CAT6500-RC2TXL#sh platform hardware capacity | begin L3 Forwarding Resources L3 Forwarding Resources FIB TCAM usage: Total Used %Used 72 bits (IPv4, MPLS, EoM) 1048576 465980 44% 144 bits (IP mcast, IPv6) 524288 14903 3% 288 bits (IPv6 mcast) 262144 1 1% detail: Protocol Used %Used IPv4 465978 44% MPLS 1 1% EoM 1 1% IPv6 14894 3% IPv4 mcast 9 1% IPv6 mcast 1 1% Adjacency usage: Total Used %Used 1048576 32018 3%
Sup720BXL output of "sh platform hardware capacity": (FIB TCAM partitioned with "mls cef maximum-routes ip 768") CAT6500-RC720BXL#sh platform hardware capacity | begin L3 Forwarding Resources L3 Forwarding Resources FIB TCAM usage: Total Used %Used 72 bits (IPv4, MPLS, EoM) 802816 467348 58% 144 bits (IP mcast, IPv6) 122880 14970 12% detail: Protocol Used %Used IPv4 467338 58% MPLS 9 1% EoM 1 1% IPv6 14963 12% IPv4 mcast 4 1% IPv6 mcast 3 1% Adjacency usage: Total Used %Used 1048576 1481 1% The release notes say: -XL mode: · IPv4 and MPLS: Up to 1,007,000 routes · IPv4 multicast and IPv6 unicast and multicast: Up to 503,000 routes "These are the theoretical maximum numbers of routes for the supported protocols (the maximums are not supported simultaneously):" The above output of the Sup2T-XL seems to say that the Sup2T-XL has a larger FIB TCAM (2M) than the Sup720-BXL.
