locally. The Cisco VXC 2100 series attaches to the Cisco Unified IP Phone 8961, 9951, and 9971 through a

spine connector cable.

When running VXC with a single-tunnel option, high traffic to or from VXC may affect the phone's

performance. Cisco Unified IP Phones 8961, 9951 and 9971 support 384kbps throughput bandwidth for VXC.

Set VPN MTU to 1406 to reduce packet reassemble in Cisco Unified IP Phones 8961, 9951 and 9971, to

improve bandwidth in limited packet rate.

Video and audio applications may not play smoothly through VXC, even on a device plugged directly into a

LAN.

USB CD-ROMs and other USB storage devices have limited support. In the current VXC environment, the

expected performance is a low bit/transfer rate for USB storage devices and USB CD-ROMs connected to

the VXC device.
