Displaying port mirroring and monitoring information
The mirror port feature lets you connect a protocol analyzer to a port on a Brocade device to
observe the traffic flowing into and out of another port on the same device. To use this feature, you
specify the port you want to monitor and the port into which you are plugging the protocol analyzer.
NOTE
ServerIron supports more than one active mirror port at a time. By default, no mirror port is
assigned.
To display the current port mirroring and monitoring configuration, enter the following command.
ServerIronADX(config)# show monitor
Mirror Interface: ethernet 4/1
Monitored Interfaces:
Both Input Output
---------------------------------------------------
ethernet 4/3
In this example, port 4/1 is the mirror interface, to which the software copies (“mirrors”) the traffic
on port 4/3. In this case, both directions of traffic on the monitored port are mirrored to port 4/1.
Syntax: show monitor
If only the incoming traffic is mirrored, the monitored interface is listed under Input. If only the
outbound traffic is mirrored, the monitored interface is listed under Output.
Setting QoS priority
You can set the Quality-of-Service (QoS) priority level for a port, VLAN, static MAC address, or Layer
4 session. You can select the normal queue or the high priority queue. All traffic is in the normal
queue by default. When you allocate a port, VLAN, static MAC address, or Layer 4 session to the
high-priority queue, all traffic queued up for that item is processed before any traffic in the normal
queue for the same item is processed.
QoS applies to outbound traffic only.
To set the QoS priority level, enter commands such as the following.
ServerIronADX(config)# interface e 6
ServerIronADX(config-if-6)# qos-priority high
Syntax: [no] qos-priority normal | high
Turning the flow control on or off
By default, flow control is on. To turn flow control (802.3x) for full-duplex ports on or off, enter the
following command.
ServerIronADX(config)# no flow-control
Or assign it to a specific interface.
ServerIronADX(config)# int e5/2
ServerIronADX(config-if-5/2)#no flow control
Syntax: [no] flow-control
