Fixed-Port Switch HP 6208M-SX and Routing Switch HP 6308M-SX
Figure 8.15 shows the HP 6308M-SX. Figure 8.16 shows the HP 6208M-SX. Each device provides a serial port
for CLI management and eight 100Mbps SX fiber ports for connection to Gigabit Ethernet links.
The HP 6308M-SX routing switch provides both Layer 2 switching and Layer 3 routing in a single device and
supports all of the most popular standards-based protocols—IP, IP/RIP, IPX, OSPF, BGP4, and AppleTalk. HP
routing switches also support two IP multicasting protocols—Distance Vector Multicast Routing Protocol (DVMRP)
and Protocol Independent Management (PIM).
within a network provided by the Standby Router Protocol (SRP).
HP 6308M-SX routing switches can be concentrated in a data center to provide additional port density for very
high-performance, centralized routing. A stack of HP 6308M-SX routing switches can provide connections to
routers, switches, and servers.
The HP 6208M-SX switch provides support for Layer 2 and Layer 3 switching within one platform.
The HP 6208M-SX switch can be used to interconnect a stack of backbone switches for faster switching and
access over Gigabit links. This switch also can be stacked with other HP 6208M-SX switches in a network center
to provide Gigabit link connections to switches and server farms through the riser.

System Architecture

Chassis Architecture
Built on a fully non-blocking architecture, the chassis platform provides switching capacity in the core and on each
interface module of up to 128 Gbps for the HP 9304M and 256 Gbps for the HP 9308M.
The chassis core consists of a backplane and crosspoint switching fabric that supports four interfaces modules on
the HP 9304M. The HP 9308M supports eight interface modules.
Each interface module utilizes a high bandwidth, shared memory switching fabric that switches up to 32 Gbps of
bandwidth. This local switching fabric houses the forwarding engines and includes Application Specific Integrated
Circuits (ASICs) that provide packet switching functions such as priority handling. Each interface module also
contains ASICs that perform high speed Layer 2, Layer 3, and Layer 4 lookups and forwarding, including IP sub-
net look ups and packet modifications of IP and IPX packets. Additionally, each interface module has an 8 Gbps
full-duplex data path to the backplane that provides separate priority queues for each module destination.
Th
e routing switches also support path redundancy for hosts
