Port Fencing

Port Fencing is a policy-based feature that allows the user to set thresholds on port events. If the port
generates more events in a user-specified time period than you think is acceptable, Port Fencing
blocks the port, disabling transmit and receive traffic until you have a chance to investigate, solve
the problem, and manually unblock the port.
Access the Port Fencing Policy dialog box by selecting Configure > Port Fencing. The Port Fencing
dialog box displays the existing policies that are discovered on HP directors and switches running
firmware 07.x and later. Use this dialog to name a policy, set the limit and period and select objects
to which to apply the policy. If a switch does not support Port Fencing, the ISL threshold box displays
a Port Fencing Not Supported message.

Configuring Port Fencing

To configure port fencing, the following requirements must be met:
• To configure Port Fencing, you must have one of the following models, which must be running
firmware 7.0 or later:
• Edge Switch 2/16
• Edge Switch 2/24
• Edge Switch 2/32
• Director 2/64
• Director 2/140
Firmware 7.x supports ISL protocol fencing only. Firmware 8.x supports ISL protocol, link fencing,
and security fencing. All switches must be discovered directly using MPI.

Adding thresholds

HAFM allows you to manage ISL protocol, link, and security thresholds.

Adding ISL Protocol thresholds

Use an ISL protocol threshold to block a port when one of the following ISL protocol errors meets the
threshold:
• ISL Bouncing—ISL has repeatedly become unavailable due to link down events.
• ISL Segmentation—ISL has repeatedly become segmented.
• ISL Protocol Mismatch—ISL has been repeatedly put into the Invalid Attachment state due to a
protocol error.
To add ISL Thresholds:
1. Select Configure > Port Fencing.
