Overview of the TokenSpeed Module

Filtering

The TokenSpeed module has the following ﬁltering features:

•Support for NetBIOS name ﬁlters, datagram broadcast ﬁlters, and a name query interval

•Filtering for any pattern up to 12 bytes wide in the ﬁrst 255 bytes of a frame

•Per-port ﬁlter conﬁguration

Caching and Proxy

The TokenSpeed module has the following caching and proxy features:

•Caching for NetBIOS names to reduce NetBIOS name broadcast packets (Each switch can cache up to 500 NetBIOS names.)

•Caching for Route Information Field (RIF) to speed up the explorer process and reduce broadcasts (Each switch can cache up to 500 unique RIFs.)

•Cache capacity of up to 128 RIFs for source route explorer proxy and 5120 media access control (MAC) addresses

•Cache capacity of up to 10,240 MAC addresses in the MCP station table

Fault Tolerance

The TokenSpeed module has the following fault-tolerance features:

•Ability to install, remove, and replace a module in an operational chassis (hot-swap)

•Flash memory download with storage for two conﬁgurations on the TokenSpeed/MCP module

•Software update and management access over the network or a serial connection to the TokenSpeed/MCP module

Network Management

The TokenSpeed/MCP module provides the following network management features for the TokenSpeed module and other modules in a Centillion switch:

•Simple Network Management Protocol (SNMP) agent with Centillion Management Information Base (MIB) extensions
