Enabling long distance when connecting to TDM devices
Use this procedure when connecting to Time-Division Multiplexing (TDM) devices and your Brocade
switch has QoS and buffer credit recovery enabled.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Disable QoS.
switch:admin> portcfgqos --disable [slot/]port
If you do not disable QoS, after the second or third Link Reset (LR), ARBS display.
