7.
Configure the DCBX protocol (CEE in this example).
Dell(conf)#
interface twentyFiveGigE 1/8/1
Dell(conf-if-tf-1/8/1)#
protocol lldp
Dell(conf-if-tf-1/8/1-lldp)#
dcbx version cee
8.
Assign a VLAN ID to the switch port to match the VLAN ID assigned to the
adapter (5).
Dell(conf)#
interface vlan 5
Dell(conf-if-vl-5)#
tagged twentyFiveGigE 1/8/1
Configuring the Arista 7060X Ethernet Switch
The following examples show Arista 7060X Switch configuration.
Configuring RoCE APP TLVs for both RoCE and RoCE v2
The following is an example of configuring RoCE APP TLV for both RoCE and
RoCE v2:
Arista-7060X-EIT(config)#
dcbx application ether 0x8915 priority 5
Arista-7060X-EIT(config)#
dcbx application udp 4791 priority 5
Mapping Priority to Traffic Class
In the following example, Priority (
cos
) 5 is mapped to traffic class 1, and the rest
of the priorities are mapped to traffic class 0.
Traffic class
in this example, refers
to a group of traffic types, where
1
is holding the RoCE traffic and
0
is the
default common group that holds all the other types of traffic:
Arista-7060X-EIT(config)#
dcbx ets qos map cos 0 traffic-class 0
Arista-7060X-EIT(config)#
dcbx ets qos map cos 1 traffic-class 0
NOTE
The VLAN ID need not be the same as the RoCE traffic class priority
number. However, using the same number makes configurations
easier to understand.
