module increases stack resiliency when failures

occur. These secondary modules receive real

time conﬁguration updates while in standby

mode. If a failure occurs, the entire stack

switches over to the redundant module to

maintain control, even in remote, unattended

networks.

OmniStack also supports a redundant power

supply to keep the switch online in the event of

primary power supply failure.

A redundant stacking link conﬁguration is

implemented by using the new redundant

stacking module and connecting it to OmniStack

Unit 1 (normally the bottom unit in a stack with

primary management module). When any unit in

the stack goes down, another path is conﬁgured

to continuously forward packets around

the fault.

Trafﬁc allocation

Trafﬁc allocation to class of service (CoS)

enables more predictable IP trafﬁc delivery of

priority data by assigning different delivery

status for each application at the edge of the

network (OmniStack). Enterprises can classify

mission-critical applications like voice or video

as priority trafﬁc from end-to-end. Other trafﬁc,

like e-mail and web browsing, can be labeled

lower priority. Trafﬁc allocation to CoS is based

on 802.1p and DSCP* for multi-media or real-

time applications.
