Configuring SIP Snooping SIP Snooping Use Case
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 14-13
SIP Condition
In this example, specific QoS treatments are configured based on the source IP subnet.
• Voice source IP subnet 10.10.0.0 = DSCP 56
• Video source IP subnet 10.10.0.0=DSCP 32
• Voice source IP subnet 10.20.0.0 = DSCP 46
• Video source IP subnet 10.20.0.0=DSCP 48
The SIP conditions are configured as follows:
-> policy condition Voice_srcip_SIP1 source ip 10.10.0.0 mask 255.255.0.0 sip
audio
-> policy condition Video_srcip_SIP1 source ip 10.10.0.0 mask 255.255.0.0 sip
video
-> policy condition Voice_srcip_SIP2 source ip 10.20.0.0 mask 255.255.0.0 sip
audio
-> policy condition Video_srcip_SIP2 source ip 10.20.0.0 mask 255.255.0.0 sip
video
-> policy action DSCP56 dscp 56
-> policy action DSCP32 dscp 32
-> policy action DSCP46 dscp 46
-> policy action DSCP48 dscp 48
-> policy rule Voice_srcip_SIP1_rule condition Voice_srcip_SIP1 action DSCP56
-> policy rule Video_srcip_SIP1_rule condition Video_srcip_SIP1 action DSCP32
-> policy rule Voice_srcip_SIP2_rule condition Voice_srcip_SIP2 action DSCP46
-> policy rule Video_srcip_SIP2_rule condition Video_srcip_SIP2 action DSCP48
-> qos apply
