99 Dell EMC PowerEdge MX SmartFabric Configuration and Troubleshooting Guide
The following example shows interface ethernet 1/2 that has auto negotiation enabled on the interface:
Nexus-3232C-Leaf1(config-if)# do show int eth 1/2
Ethernet1/2 is down (XCVR not inserted)
admin state is down, Dedicated Interface
Hardware: 40000/100000 Ethernet, address: 00fe.c8ca.f367 (bia 00fe.c8ca.f36c)
MTU 1500 bytes, BW 100000000 Kbit, DLY 10 usec
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, medium is broadcast
auto-duplex, auto-speed
Beacon is turned off
Auto-Negotiation is turned on, FEC mode is Auto

12.5.5 Verify LACP
The interface status of the upstream switches can provide valuable information for the link being down. The
following example shows interfaces 1 and 3 on upstream Cisco Nexus switches as members of port channel
1:
3232C-Leaf2# show interface status
--------------------------------------------------------------------------------
Port Name Status Vlan Duplex Speed Type
--------------------------------------------------------------------------------
mgmt0 -- connected routed full 1000 --
Eth1/1 To MX Chassis 1 suspended trunk full 100G QSFP-100G-SR4
Eth1/2 -- xcvrAbsen routed auto auto --
Eth1/3 To MX Chassis 2 suspended trunk full 100G QSFP-100G-SR4
---- OUTPUT TRUNCATED -----
Checking interface 1 reveals that the ports are not receiving the LACP PDUs as shown in the following
example:
3232C-Leaf2# show int eth 1/1
Ethernet1/1 is down (suspended(no LACP PDUs))
admin state is up, Dedicated Interface
Belongs to Po1

NOTE: In Dell EMC Networking switches, use show interface status command to view the interfaces
and associated status information. Use show interface ethernet interface number to view the
interface details.
In this example, the errors listed above occurred because an uplink was not created on the fabric.
