54 Metro Ethernet Routing Switch 8600 modules
The 8681XLR module supports up to 128 000 table entries in its forwarding
engine, allowing for large Layer 2 and Layer 3 configurations, including
Internet routing tables. For information about table entry characteristics, see
Network Design Guidelines (313197-E).
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 modules only.
• R mode supports up to:
— 256 000 IP routes
— 64 000 MAC entries
— 32 000 ARP entries
This mode supports R modules only.
The 8681XLR 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) .
8681XLW module
The 8681XLW module ( "8681XLW module" (page 54) ) provides a
single 10GBaseLW 1310nm 10 Gigabit Ethernet serial WAN port. The
10GBaseLW port (9.95 Gb/s WAN PHY) operates in full-duplex mode and
provides a transmission range of up to 10 km using 9/125
µ
m single-mode
fiber cable.
Note that the Metro Ethernet Routing Switch 8600 does not support the
8681XLW module.
