Note 1: The 8003 chassis is not supported with Metro Ethernet Routing Switch 8600.

Note 2: For information about these Media Dependent Adapters (MDA), see "8672ATME and 8672ATMM modules" (page 50). The 8672ATME and 8672ATMM modules are not supported with Metro Ethernet Routing Switch 8600 Ethernet VPN services.

Note 3: Metro Ethernet Routing Switch 8600 does not support the 8681XLR and 8681XLW modules.

Note 4: For information about these MDAs, see "8683POSM module" (page 56). The 8683POSM module is not supported with Metro Ethernet Routing Switch 8600 Ethernet VPN services.

Metro Ethernet Routing Switch 8600 pre-E, E, and M modules feature set

Each Metro Ethernet Routing Switch 8600 pre-E, E, or M module consists of a Backplane Forwarding Module (BFM) with common application specific integrated circuits (ASIC) on each module. These ASICs provide a forwarding engine and local storage of Layer 2 to 4 forwarding tables. Each forwarding engine provides lookups, resolves addresses and sends packets through the switch fabric to a destination port without CPU intervention. The forwarding engine also filters packets against current prioritization policies and can set prioritization information in the internal packet header.

The BFM is also equipped with eight priority queues per port. You can use either of the following two prioritization schemes:

•Strict priority

•Weighted Round Robin (WRR)

Strict priority guarantees the highest priority. WRR gives priority based on a round robin algorithm. For more information about prioritization schemes see Network Design Guidelines (313197-E).

Output buffer memory consists of 8 MB of memory allocated to each Gigabit Ethernet port or shared among eight 10/100 ports.

Note that Metro Ethernet Routing Switch 8600 does not support pre-E modules.

Metro Ethernet Routing Switch 8600 R module feature set

Each Metro Ethernet Routing Switch 8600 R module (Release 4.0 and later) consists of a Distributed Processing Module (DPM) as well as a Port Interface Module (PIM). The PIM consists of various Media Access Controls
