Ethernet Port Commands
Description
This command specifies sliding window size over which the ethernet frames are sampled to detect signal fail
or signal degrade conditions. The command is used jointly with the sf-threshold and the sd-threshold to
configure the sliding window size.
Default
10 seconds
Parameters
seconds — The size of the sliding window in seconds over which the errors are measured.
Values
down-on-internal-error
Syntax [no] down-on-internal-error
Context config>port>ethernet
Description
This command configures the system to allow to bring a port operationally down in the event the systems
has detected internal max transmit errors.
Default no down-on-internal-error
dot1q-etype
Syntax dot1q-etype 0x0600..0xffff
no dot1q-etype
Context config>port>ethernet
Description
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.
