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.

3. Disable the credit recovery; credit recovery is not compatible with the IDLE mode. If you do not 

disable the credit recovery, it continues to perform a link reset.

switch:admin> portcfgcreditrecovery --disable [slot/]port

4. Configure the port to support long-distance links. 

switch:admin> portcfglongdistance [slot/]port,LS,0,100
