This command specifies the Ethertype expected when the port's encapsualtion type is dot1q. Dot1q
encapsulation is supported only on Ethernet interfaces.
When the dot1-etype is configured to a value other than 0x8100 (the default value) on a port, the outermost
tag in the received packet is matched against the configured value and if there is a match then it is treated as
a Dot1q packet and the VLAN ID is used to match against the configured Dot1q SAPs on the port to find the
Dot1q SAP the packet should be matched to.
NOTES:
This command does not change the etype used to match the inner tag for a QinQ SAP. The 7210 SAS
devices always uses 0x8100 for matching the inner tag etype. In other words, if this command is config-
ured on a port configured for QinQ encapsulation, then it is ignored and 0x8100 is used always.
This command takes effect only for access ports and hybrid ports. On hybrid ports, it applies to all traf-
fic (that is, traffic mapped to SAPs and network IP interfaces). It is not supported for network ports.
Dot1q-preserve SAPs cannot be configured on dot1q encap ports configured to use ethertype other than
0x8100.
Priority tagged packet received with etype 0x8100 on a dot1q port configured with etype 0x9100 is
classified as a priority tagged packet and mapped to a dot1q:0 SAP (if configured) and the priority tag is
removed.
Priority tagged packets received with etype 0x6666 (any value other than 0x8100) on a dot1q port con-
figured with etype 0x9100 is classified as null-tagged packet and mapped to a dot1q:0 SAP (if config-
ured) and the priority tag is retained and forwarded as expected.
The maximum number of unique dot1q-etypes configurable per node is limited. The resources needed
for configuration of dot1q-etype is shared by the default dot1q-etype, default qinq-etype and user con-
figured values for qinq-etype. In other words, the number of unique dot1q-etypes allowed decreases, if
the number of unique qinq-etype configured is more. The converse is also true.
The no form of this command reverts the dot1q-etype value to the default.
Parameters 0x0600..0xffff — Specifies the Ethertype to expect.
Default If the encap-type is dot1p, then the default is 0x8100.
If the encap-type is qinq, then the default is 0x8100.
Values <0x0600..0xffff> : [1536..65535] - accepts in decimal or hex
