Tunneling and BA Classifiers

BA classifiers can be used with GRE and IP-IP tunnels on the following platforms:

M7i and M10i
M-series with E-FPC or EP-FPC
M120
M320
T-series

When a GRE or IP-IP tunnel is configured on an incoming (core-facing) interface, the queue number and PLP information are carried through the tunnel. At the egress (customer-facing) interface, the packet is queued and the CoS bits rewritten based on the information carried through the tunnel.

If no BA classifier is configured in the incoming interface, the default classifier is applied. If no rewrite rule is configured, the default rewrite rule is applied.
