Release Information

Statement introduced in Release 10.1 of Junos OS.

Description

Configure the DSCP value to mark the DSCP bits in the IP header packets generated by SRX Series Integrated Convergence Services for voice calls. Based on the DSCP bits setting, packets are given priority queuing on the egress interface if a QoS filter is configured and applied to the interface. The QoS filter can classify the RTP packets and direct them to a higher priority queue to achieve improved voice quality when traffic is congested.

Note: Integrated Convergence Services marks only RTP packets of calls that it terminates, which include calls to peer call servers and peer proxy servers that provide SIP trunks. If a call is not terminated by Integrated Convergence Services, then DSCP marking does not apply. Pass-through traffic is not affected.

A media policy consists of parts that match parameters in the from clause and specify actions to execute in the then clause. For calls that match the specified conditions, the device changes the DSCP bits setting to the configured value.

Options

media-policy-name—Name given to the policy.

term-name—Name of the term that the policy defines.

fqdn—FQDN as the address.

ipv4-address—IPv4 address.

dscp-value—6-bit bitmap in the IP header used by devices to decide the forwarding priority of packet routing.
