Ternary content-addressable memory (TCAM) devices are increasingly used in the Industry for performing high-speed packet classification. show sprom backplane 1 | grep “Serial”. icmp 0 24. Its utilization depends on the features supported by the platform, but the TCAM is generally partitioned into sections designated for unicast routes, multicast routes, VLANs, and entries for routed, VLAN, and QoS ACLs. I'd like to be able to monitor how much data is being handled by each port, to try and identify a possible rogue device flooding the network with packets. txt) or read online for free. show platform hardware qfp active tcam resource-manager usage. After the issue earlier this year with the Cisco routers hitting the limit of 512k routes in hardware I think I have to clarify how many routes the Cisco 3850 platform supports. Ie: If the my template is "default desktop" they support a number of indirect IPv4 routes of 2k. cisco WS-C6509-E (R7000) processor (revision 1.

I dropped the ARP timeout value to 30 minutes to match the WLC session timeout and 6,000 of the ARP entries were purged, dropping the TCAM utilization to 65% and CPU load down to 10%. x/26 fragment routeable 0x1 [0] It always comes together with 'normal' entries like these:.
