Usage Information For details about using this command, see the “NIC Teaming” section of the Layer 2 chapter in the Dell
Networking OS Configuration Guide.
To disable the ARP refresh feature, use the no mac-address-table station-move refresh-arp
command.
Use this command in Configuration Terminal Batch mode to refresh the egress interface in a dual-homing setup.
mac-address-table station-move threshold
Specify the threshold and time interval for the maximum number of station moves on PE ports. When the number of station moves for a
specified MAC address exceeds the configured threshold in the configured time, a loop is detected on PE ports. The loop is prevented by
bringing down the line protocol on all active ports in the learned path, except for the port with the lowest interface index (ifIndex).
C9000 Series
Syntax

Parameters

station move is detected within the configured interval. The range is from 5 to 50.
interval seconds Enter the keyword interval with the interval (in seconds). The range is from 1 to 60.

Command History
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.10(0.0) Introduced the Configuration Terminal Batch mode on C9010.
9.9(0.0) Introduced on the C1048P.
Usage Information
As xSTP protocols are not supported on PEs, use this command to detect possible loops on PE ports.
Use this command in Configuration Terminal Batch mode to detect the possible loops in a dual-homing setup.
If a station move for a MAC address is detected above the configured threshold and within the specified time, a
syslog message is triggered with the port information. All ports on which the station move was detected are shut
