Fault Symptom
The outbound interface of the switch joins a VLAN in untagged mode. When the
remark 802.1p command is configured on the outbound interface, the configuration is invalid.
Cause Analysis
The configuration of the
S5700(such as
S5700-28P-LI-AC)is as follows:
#
traffic classifier test
if-match any
traffic behavior test
remark 8021p 2
traffic policy test
classifier test behavior test
#
interface GigabitEthernet1/0/1
port link-type access
port default vlan 10
traffic-policy test outbound
#
The outbound interface joins a VLAN in untagged mode, so VLAN tags are removed from packets sent by the interface.
Conclusion
To apply traffic policy defining
remark vlan to the outbound interface, ensure that the interface joins a VLAN in tagged mode.
