Layer 3 GEM

The Layer 3 GEMs (N55-M160L3 and N55-M160L3-V2 ), shown in Figure 1-6, provide 160 Gbps of Layer 3 services. The expansion modules are field-replaceable units (FRU’s). The N55-M160L3-V2 uses a newer version of the Layer 3 ASIC that enables higher table sizes in a future software release from 8K host entries to 16K host entries or from 4K multicast routes to 8K multicast routes (IPv4).
