NETGEAR 8800 Chassis Switch CLI Manual Default N/A. Usage Guidelines This command shows the current number of IP routes and local and remote IPv4 hosts in the LPM hardware table. It also shows the number of IPv4 unicast, multicast, and IPv6 unicast entries in the Layer 3 hardware hash table. The theoretical maximums for each individual resource type are shown at the bottom of the output. These maximum values cannot all be achieved simultaneously, and individual values might not be reached depending on the addresses or routes in use. The NETGEAR 8800 software supports the coexistence of higher- and lower-capacity hardware in the same NETGEAR 8800 chassis. To allow for coexistence and increased hardware forwarding, when the number of IPv4 routes exceeds 25,000, the lower-capacity hardware automatically transitions from using LPM routing to forwarding of individual remote hosts, also known as IP Forwarding Database (IP FDB) mode. Higher-capacity hardware continues using LPM routing. Lower capacity hardware operating in IP FDB mode will be indicated with a d flag in the output of show iproute reserved-entries statistics command, indicating that only direct routes are installed. For more information, see the section "Coexistence of Higher- and Lower-Capacity Hardware" in the NETGEAR 8800 User Manual. Example The following command displays usage statistics for the LPM and Layer 3 hardware tables: (Demo) XCM8806.6 # show iproute reserved-entries statistics |-----In HW Route Table----| |--In HW L3 Hash Table--| # Used Routes # IPv4 Hosts IPv4 IPv4 IPv6 IPv4 Slot Type IPv4 IPv6 Local Remote Local Rem.
