Configuring Layer 2 Circuit Cross-Connect Match Conditions

Table 1 describes the firewall filter match conditions for Layer 2 circuit cross-connect (CCC) traffic.

To configure firewall filter match conditions for Layer 2 CCC traffic:

  • Include the match-conditions statement at the [edit firewall family ccc filter filter-name term term-name from hierarchy level.

Table 1: Layer 2 Circuit Cross-Connect Firewall Filter Match Conditions

Match ConditionDescription

forwarding-class class

Forwarding class. Specify assured-forwarding, best-effort, expedited-forwarding, or network-control.

forwarding-class-except
class

Do not match on the forwarding class. Specify assured-forwarding, best-effort, expedited-forwarding, or network-control.

interface-group group-number

Interface group on which the packet was received. An interface group is a set of one or more logical interfaces. For group-number, specify a value from 0 through 255. For information about configuration interface groups, see Applying Firewall Filters to Interfaces.

interface-group-except number

Do not match on the interface group in which the packet was received. For group-number, specify a value from 0 through 255.

loss-priority level

Packet loss priority (PLP) level. Specify a single level or multiple levels: low, medium-low, medium-high, or high.

Supported on MX Series routers; M120 and M320 routers; and M7i and M10i routers with the Enhanced CFEB (CFEB-E).

On M320 routers, you must enable the tricolor statement at the [edit class-of-service] hierarchy level to commit a PLP configuration with any of the four levels specified. If the tricolor statement is not referenced, you can only configure the high and low levels. This applies to all protocol families.

For information about using behavior aggregate (BA) classifiers to set the PLP level of incoming packets, see the JUNOS Class of Service Configuration Guide.

loss-priority-except level

Do not match on the packet loss priority level. Specify a single level or multiple levels: low, medium-low, medium-high, or high.

For information about using behavior aggregate (BA) classifiers to set the PLP level of incoming packets, see the JUNOS Class of Service Configuration Guide.
