46Metro Ethernet Routing Switch 8600 modules

The Metro Ethernet Routing Switch 8600 system has three hardware operating modes:

Default mode (32 000 table entries) supports up to 32 000 hardware records. This mode supports all modules.

M mode (128 000 table entries) supports up to 128 000 hardware records. This mode supports M and R modules only.

When used in the Enterprise mode of operation, R mode supports up to:

256 000 IP routes

64 000 MAC entries

32 000 ARP entries

This mode supports R modules only.

For information about Ethernet VPN characteristics, see Engineering Guidelines for Metro Ethernet Routing Switch 8600 and Metro Ethernet Services Unit 1800/1850.

The 8648GTR module supports R and M mode. For specific R and M mode configuration requirements, see "R mode configuration requirements" (page

24)and "M mode configuration requirements" (page 23).

8648TXE and 8648TXM modules

The 8648TXE and 8648TXM modules ("8648TXE/8648TXM module" (page 46)) provide 48 autonegotiating 10BaseT/100BaseTX ports using 8-pin modular (RJ-45) connectors. Ports operate either at 10 Mb/s or 100 Mb/s up to distances of 100 m with Category-3 or greater unshielded twisted pair (UTP) cable.
