Parameters
Usage Guidelines
UUse this command to mark traffic from the source network/host. Use the mark option to specify the type of service
(tos) and priority value. The tos value is marked in the IP header. The 802.1p priority value is marked in the frame.
r When the interface receives the packet, its content is checked against the ACE’s in the ACL. It is marked based on the
ACL configuration.
Example
The example below marks the type of service (tos) value to 254 for all traffic coming from the source network.
RFS7000(config)#access-list 3 mark tos 254 xxx.xxx.3.0/24
RFS7000(config)#access-list 3 permit any
