encapsulation dot1q
Configures lite-subinterfaces.
Syntax
encapsulation dot1q vlan-id
To remove a previously configured lite-subinterface, use the no encapsulation dot1q vlan-id
command.
Parameters
dot1q vlan-id Enter the keyword dot1q followed by the VLAN ID to which the host belongs. The range
is from 1 to 4094. A lite subinterface is considered as a Layer 3 port property and is
synchronous with the existing rules of applying Layer 2 or Layer 3 properties to an
interface.

9.3.0.0 Introduced on the S6000.
9.2(1.0) Introduced on the Z9500.
Usage Information
To enable routing of RRoCE packets, the VLAN ID is mapped to the default VLAN ID of 4095 and this mapping is
performed using VLAN translation. After VLAN translation, the RRoCE packets are considered in the same
manner as normal IP packets that received on L3 interface and routed in the egress direction. At the egress
interface, the VLAN ID is appended to the packet and transmitted out of the interface as a tagged packet with
the dot1Q value preserved. The dot1Q value is preserved only for egress interfaces that are associated with a
VLAN or a lite-subinterface . If a Layer 3 interface is configured without the encapsulation 802.1Q VLAN ID or is
an untagged interface in a VLAN , the dot1Q value is not preserved .
flowcontrol
Enable and disable link-level flow control (802.3x pause frames) on an interface and (optionally) configure buffer thresholds for pause and
offset frame transmission.
C9000 Series
Syntax
flowcontrol {rx {off | on} tx {off | on} [pause-threshold {1-12480}] | [resume-
offset {1-12480}] | monitor session-ID
Parameters
rx on Enter the keywords rx on to process the received flow control frames on this port.
rx off Enter the keywords rx off to ignore the received flow control frames on this port.
tx on Enter the keywords tx on to send control frames from the port to the connected device
when a higher rate of traffic is received.
tx off Enter the keywords tx off so that flow control frames are not sent from this port to
the connected device when a higher rate of traffic is received.
pause-threshold Enter the keyword pause-threshold to configure the buffer threshold (in Kilobytes)
at which the interface starts transmitting pause frames for link-level flow control. Valid
values are 1 to 12480KB. The default is 60KB.
resume-offset Enter the keyword resume-offset to configure the buffer threshold (in Kilobytes) at
which the interface resumes transmitting offset frames for link-level flow control. Valid
values are 1 to 12480KB. The default is 9KB.
