Port mirroring commands
See Avaya Ethernet Routing Switch 2500 Series Configuration — System Monitoring
(NN47215-502) for port mirroring command information.
Use the port mirroring commands to assist in diagnostics and information gathering.
Port statistics
Use port statistics commands to display information on received and transmitted packets at
the ports. The ingress and egress counts occur at the MAC layer.
For more information regarding port statistics and commands, see Avaya Ethernet Routing
Switch 2500 Series Configuration — System Monitoring (NN47215-502).
System logs
You can use the syslog messaging feature of the Ethernet Routing Switch 2500 Series products
to manage event messages. The syslog software on the 2500 Series switch communicates
with a server software component called syslogd that resides on your management
workstation.
The daemon syslogd is a software component that receives and locally logs, displays, prints, or
forwards messages that originate from sources that are internal and external to the workstation.
For example, syslogd software concurrently handles messages received from applications
running on the workstation, as well as messages received from an Ethernet Routing Switch
2500 Series device running in a network accessible to the workstation.
For more information about system logging, see Avaya Ethernet Routing Switch 2500 Series
Configuration — System Monitoring (NN47215-502).
Auto Unit Replacement (AUR)
Enable AUR to replace a failed device in a stack.
AUR allows you to replace a failed unit in a stack with a new unit while retaining the
configuration of the previous unit. The stack power must be on during unit replacement.
