Overview 1-5

Fast EtherChannel Feature

Fast EtherChannel links provide parallel bandwidth of up to 400 Mbps (in full duplex

mode) between a Catalyst 1900 or Catalyst 2820 switch and another switch or host by

grouping two Fast Ethernet interfaces into a single logical transmission path.

Uplink Fast

UplinkFast is an enhancement to the Spanning-Tree Protocol (STP) that provides fast

convergence whenever STP picks a new root port. STP selects a new root port automatically

when a link or switch fails or when STP parameters change.

TACACS+

The TACACS+ protocol exchanges authentication information between a network device

and a centralized database. TACACS+ allows a separate access server to provide

authentication for access to the switch management console. TACACS+ is used in place of

a locally configured password.

Configuration File Upload and Download

You can use the Configuration File Upload and Download feature to specify switch

configuration commands in an ASCII file that can be uploaded to or downloaded from a

TFTP server.

When the switch powers up, it can retrieve its configuration from a TFTP server.
