Link Aggregation

Link Tracking

VLANs

6 | Before You Start
All uplink ports are configured in a single LAG (LAG 128). Server-facing ports are
auto-configured as part of link aggregation groups if the corresponding server is configured
for LACP-based NIC teaming. Static LAGs are not supported.
Tip: The recommended LACP timeout is long-timeout mode.
By default, all server-facing ports are tracked by the operational status of the uplink LAG. If
the uplink LAG goes down, the Aggregator loses its connectivity and is no longer
operational; all server-facing ports are brought down.
Tip: If installed servers do not have connectivity to a ToR switch, check the Link Status LED
of uplink ports on the Aggregator. If all LEDs are on, check the LACP configuration on the
ToR switch that is connected to the Aggregator to ensure the LACP is correctly configured.
Note:
Link tracking is also referred to as uplink failure detection (UFD).
By default, all Aggregator ports belong to all 4094 VLANs and are members of untagged
VLAN 1. You can use the CLI or CMC interface to configure only the required VLANs on a
port.
When you configure VLANs on server-facing interfaces (ports 1 to 32), you can assign
VLANs to a port or a range of ports by entering the vlan tagged or vlan untagged commands
in interface configuration mode; for example:
FTOS(conf)# interface tengigabitethernet 0/2 - 4
FTOS(conf-if-range-te-0/2-4)# vlan tagged 5,7,10-12
FTOS(conf-if-range-te-0/2-4)# vlan untagged 3
Note:
You can also use the CMC interface to configure VLANs.

Uplink LAG

The tagged VLAN membership of the uplink LAG is automatically configured based on the
VLAN configuration of all server-facing ports (ports 1 to 32).
The untagged VLAN used for the uplink LAG is always the default VLAN.

Server-Facing LAGs

The tagged VLAN membership of a server-facing LAG is automatically configured based on
the server-facing ports that are members of the LAG.
