- Check interface link status on the cluster. In the below example, node 4 has NO-CARRIER which means no connection to the secondary-0 interface.
Command:
# viprexec -i 'ip link show | egrep "slave-|public"'
Example:
admin@node1:~> viprexec -i 'ip link show | egrep "slave-|public"' Output from host : 1xx.1xx.219.1 bash: public: command not found 3: slave-0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master public state UP mode DEFAULT group default qlen 1000 5: slave-1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master public state UP mode DEFAULT group default qlen 1000 10: public: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default Output from host : 1xx.1xx.219.2 bash: public: command not found 3: slave-0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master public state UP mode DEFAULT group default qlen 1000 5: slave-1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master public state UP mode DEFAULT group default qlen 1000 10: public: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default Output from host : 1xx.1xx8.219.3 bash: public: command not found 4: slave-0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master public state UP mode DEFAULT group default qlen 1000 5: slave-1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master public state UP mode DEFAULT group default qlen 1000 10: public: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default Output from host : 1xx.1xx.219.4 bash: public: command not found 2: slave-0: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc mq master public state DOWN mode DEFAULT group default qlen 1000 5: slave-1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master public state UP mode DEFAULT group default qlen 1000 10: public: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default
- Confirm that there is a detected link by the individual interfaces:
Command:
# viprexec -i "echo slave-0;sudo ethtool slave-0 | grep 'Link detected:';echo slave-1;sudo ethtool slave-1 | grep 'Link detected:'"
Example:
admin@node1:~> viprexec -i "echo slave-0;sudo ethtool slave-0 | grep 'Link detected:';echo slave-1;sudo ethtool slave-1 | grep 'Link detected:'" Output from host : 1xx.1xx.219.1 slave-0 Link detected: yes slave-1 Link detected: yes Output from host : 1xx.1xx.219.2 slave-0 Link detected: yes slave-1 Link detected: yes Output from host : 1xx.1xx.219.3 slave-0 Link detected: yes slave-1 Link detected: yes Output from host : 1xx.1xx.219.4 slave-0 Link detected: no slave-1 Link detected: yes
- Confirm if the switches are Arista on Gen 1 or Gen 2, and Dell (or other model) on Gen 3 environments.
NOTE: If the switches are not Arista or Dell switches, they are user-managed switches. We must notify the user that they have a connection down to remediate.
Command:
# viprexec -i "sudo lldpcli show neigh | grep SysDescr"
Example:

- Check public interface configuration for bonding secondary-0 and secondary-1 for public on the node showing no link that is detected from the command in step 2:
Command:
# sudo cat /etc/sysconfig/network/ifcfg-public
Example:
admin@node4:~> sudo cat /etc/sysconfig/network/ifcfg-public BONDING_MASTER=yes BONDING_MODULE_OPTS="miimon=100 mode=4 xmit_hash_policy=layer3+4" BONDING_SLAVE0=slave-0 BONDING_SLAVE1=slave-1 BOOTPROTO=static IPADDR=xxx.xxx.xxx.xxx/xx MTU=1500 STARTMODE=auto
- Confirm the correct Link aggregation Control Protocol (LACP) parameter is set on the nodes. (IEEE 802.3ad Dynamic link aggregation is the default setting and is expected.)
Command:
# viprexec -i "grep Mode /proc/net/bonding/public"
Example:
admin@node1:~> viprexec -i "grep Mode /proc/net/bonding/public" Output from host : 1xx.1xx.219.1 Bonding Mode: IEEE 802.3ad Dynamic link aggregation Output from host : 1xx.1xx.219.2 Bonding Mode: IEEE 802.3ad Dynamic link aggregation Output from host : 1xx.1xx.219.3 Bonding Mode: IEEE 802.3ad Dynamic link aggregation Output from host : 1xx.1xx.219.4 Bonding Mode: IEEE 802.3ad Dynamic link aggregation
- Confirm that the connections are consistent to the ports and the interfaces are connected by running the following:

If there is a NIC alert in the dmesg, it may require replacing.
- If ECS Gen 1 or Gen 2 - Provide output to ECS support hardware engineer to analysis.
- If ECS Gen 3 - Provide output to the Dell hardware team who would be expert in EX-series Hardware.

Cause
Possible causes of this issue:
- Sometimes the Small form-factor pluggable (SFP) was not properly seated during the install phase.
- User-managed switches that are done with changes that out side of our control (In the case where user-managed switches get maintained, like firmware upgrades, a link can go down and probably can get renegotiated as shown in resolution part below.)
- Failed hardware on the ECS:
- Network Interface Card
- Network Cable
- Small form-factor pluggable (SFP)
- Network switch or switch port
Resolution
Before doing any work
In the case where user-managed switches get maintained, like firmware upgrades, a link can go down and probably can get renegotiated. The example below is for secondary-0 down after a firmware upgrade done from the user on a user-managed FE switch. The below command is used for renegotiating the interface:
There are different SFP models that use either copper or fiber. Also, Back-end and Front-End switches may use different types of SFP wires. Confirm which part is required before replacing the part.

NOTE: If the interface is still down and cannot renegotiate, a Dell representative must be onsite to inspect and reseat the SPF and Cable. If this does not work, it is recommended to replace the SFP and Cable connection from the switch to the node.
There are different SFP models that use either copper or fiber. Also, Back-end and Front-End switches may use different types of SFP wires. Confirm which part is required before replacing the part.

Network cabling
The network cabling diagrams apply to U-Series, D-Series, or C-Series ECS Appliance in a Dell or customer provided rack.
To distinguish between the three switches, each switch has a nickname:
- Hare: 10 GbE public switch is at the top of the rack in a U- or D-Series or the top switch in a C-Series segment.
- Rabbit: 10 GbE public switch is located below the hare in the top of the rack in a U- or D-Series or below the hare switch in a C-Series segment.
- Turtle: 1 GbE private switch that is located below rabbit in the top of the rack in a U-Series or below the hare switch in a C-Series segment.
U- and D-Series network cabling
The following figure shows a simplified network cabling diagram for an eight-node rack configuration for a U- or D-Series ECS configured by Dell or customer. Following this figure, other detailed figures and tables provide port, label, and cable color information.

See below table for matching switches and ports and the figure for also showing the appropriate switch port numbers.
Switch 1 = Rabbit = Bottom switch
Switch 2 = Hare = Top switch
Node ports:
Secondary-0 = P01 = right port - connects to Switch 1 / Rabbit/Bottom switch.
Secondary-1 = P02 = left port - connects to Switch 2 / Hare/Top switch.

Secondary-0 = P01 = right port - connects to Switch 1 / Rabbit/Bottom switch.
Secondary-1 = P02 = left port - connects to Switch 2 / Hare/Top switch.
