Comments
All packets match the default rule.
Each dot1p-value must be explicitly
defined. Each packet can only match
a single dot1p rule.
* Each exp-value must be explicitly
defined. Each packet can only match
a single lsp-exp rule.
* This rule can only be applied on
Ethernet L2 SAP
Each ip-prec-value value must be
explicitly defined. Each packet can
only match a single prec rule.
