VAS over 10G
About the Health Check IP Address
Use this command to configure the IP addresses to be used for the VAS health check flows. Any traffic
to the configured IP address will be handled as belonging to health check flows; it will not be processed
as usual traffic and will be dropped by the SCE platform.
There are three important rules to follow when configuring the IP addresses of the VAS health check.
Improper configuration will cause the health check to fail and may cause health check traffic to be
forwarded outside of the 7600/6500.

It is required to configure a range of IP addresses (at least eight IP addresses) for the source IP. This
will insure that at least one out of the eight flows will be hashed correctly to the SCE platform. If
no range is configured and the VAS over 10G mode (MGSCP) is selected, the health check will fail
to run.
The configured IP addresses must be unique to the SCE platforms and should not exist in the
network. Any traffic to the configured IP addresses other than VAS health check traffic will be
regarded as fault traffic and be dropped by the SCE platform.
All the SCE platforms under the same EtherChannel must have the same IP address configuration.
Using the same IP addresses allows the SCE platform to correctly identify health check flows
coming from other SCE platforms (as a result of the EtherChannel hashing) and drop these flows
before they are transmitted out of the SCE platform
ip-address — Specify the IP addresses to be used for the health check:
source-ip — health check source IP address The source-ip must include a range indication
(A.B.C.D/E or A.B.C.D:0xMASK, where A,B,C,D are numbers between [0,255] and E is in the
range [0,32]. MASK is the IP mask in 8 hexadecimal characters.)
dest-ip — health check destination IP address
The configured IP addresses should not be in use in the network.
The same IP address should be used by all the SCE platforms under the same EtherChannel.
Use the no form to remove the configured IP addresses.
