System Settings
Configuring Flow Control on XGLCs
Flow control must be enabled on all XGLCs in the chassis, including active and standby redundant pairs.
The following command sequence enables flow control on an XGLC:
configue
port ethernet slot_number/1
flow-control
Notes:
• slot_number is the location of the XGLC in the ASR 5000 chassis. The XGLC is a one-port card.
You should also configure flow control at 6Gbps on the peer ports of all routers in your network that are
connected to the ASR 5000. Bidirectional flow control slows down the traffic flow rate from these routers
when the ASR 5000 sends a flow control beacon whenever an XGLC is throttled.
