736 ExtremeWare Software 7.0.0 Command Reference Guide
ESRP Commands
config esrp port-mode ports
config esrp port-mode [host | normal] ports <portlist> {don’t-count}
Description
Configures the ESRP port mode for ESRP host attach.
Syntax Description
Default
Normal.
Usage Guidelines
This feature is useful in dual-homed server environments in conjunction with high availability server
load-balancing (SLB) configurations.
Ports configured as normal ports do not accept or transmit Layer 2 or Layer 3 traffic when the local
ESRP device is a slave.
Ports configured as host ports allow configured ports that do not represent loops to the network to
continue operation independent of ESRP status. The command sets the port to forward, allowing those
ports directly attached to the slave’s hosts to communicate with other hosts that are connected to the
master.
don’t-count
has the effect of not counting the host ports and normal ports as active ports. This has the
convenience of minimal ESRP state changes due to frequent client activities like reboots and unplugging
laptops.
An L2 connection for VLANs between ESRP switches is required.
Example
The following command configures ports 1 through 5 as host ports, and prevents them from being
counted as active ports:
config esrp port-mode host ports 1-5 don’t-count
