Cisco ASR 900 Series - Configuring VC Parameters

• CEM Group — Specifies the time slots for CEM group mapping.
• Clock — Specifies the clock source for VC.
• Loopback — Sets the VC in the loopback mode.
• Overhead — Configures VC line path overhead flags.
• Shutdown — Disables the VC interface.
Configuring VC Parameters
To configure VC parameters:
enable
configure terminal
controller sdh 0/5/0
rate stm4
au-3 1
mode vc1x
tug-2 1 payload vc11
vc 1 loopback [local | network]
vc 1 clock source internal
vc 1 overhead j2 expected [16 | 64]
vc 1 overhead j2 expected message STRING
vc 1 overhead j2 tx [16 | 64]
vc 1 overhead j2 tx message STRING
vc 1 overhead v5 [0 - 7]
vc 1 [threshold bip2-sd 4 | threshold bip2-sf 4 | threshold bip2-tca 9]
end
v5 overhead should match with the far end tx v5.Note
