SmartTRUNK

Overview
This chapter explains how to configure and monitor SmartTRUNKs on the GSR. A
SmartTRUNK is DIGITAL Equipment Corporation’s technology for load balancing and
load sharing. For a description of the SmartTRUNK commands, see the “
smarttrunk
commands” section of the DIGITAL GIGAswitch/Router Command Line Interface Reference
Manual .
On the GSR, a SmartTRUNK is a group of two or more ports that have been logically
combined into a single port. Multiple physical connections between devices are
aggregated into a single logical, high-speed path that acts as a single link. Traffic is
balanced across all interfaces in the combined link, increasing overall available system
bandwidth.
SmartTRUNKs allow administrators the ability to increase bandwidth at congestion
points in the network, thus eliminating potential traffic bottlenecks. SmartTRUNKs also
provide improved data link resiliency. If one port in a SmartTRUNK should fail, its load is
distributed evenly among the remaining ports and the entire SmartTRUNK link remains
operational.
SmartTRUNK is DIGITAL’s standard for building high-performance links between
DIGITAL’s switching platforms. SmartTRUNKs can interoperate with switches, routers,
and servers from other vendors as well as DIGITAL platforms.
