Dell Technologies Networking OS10: How to Configure Port-Channels.

• Static Port-channels are statically configured. To configure static, use mode 'ON'.
• Dynamic Port-channels are dynamically configured using Link Aggregation Control Protocol (LACP). Dynamic port channels can be active or passive.
  • Mode = Active sets the interface in the Active Negotiation state with LACP. A port in Active mode can setup a port channel with another port in Active or Passive
  • Mode = Passive sets the interface in the Inactive Negotiating state, but LACP runs on the link. A passive mode link responds to active negotiation requests, but will not setup a link with another passive mode port.

Port-channel topology

Prerequisites:

1. Switches #1 and #2 exist with links between them on ports 1/1/33 and 1/1/34 (Figure 1).

Instructions

Instructions for setting up a port channel between two switches

1. Open the CLI using the console or management IP for your S-series switches #1 and #2.
2. Log in to the privileged exec mode as default admin credentials (OS10 user=admin, password=admin).
3. To modify the switch configuration on switch #1, run the configure terminal command to enter global configuration mode, then press enter.

OS10# configure terminal
OS10(config)#

4. To create port channel 1, enter the command interface port channel 1:

OS10(config)# interface port-channel 1
OS10(conf-if-po-1)#

5. To exit the interface mode, use exit:

OS10(conf-if-po-1)# exit
OS10(config)#

6. Configure which interfaces are in the port channel with interface range Ethernet 1/1/33-1/1/34:

OS10(config)# interface range ethernet 1/1/33-1/1/34
OS10(conf-range-eth1/1/33-1/1/1/34)#

7. Configure the Ethernet ports to be added to port channel 1 with active LACP using channel-group 1 mode active:

OS10(conf-range-eth1/1/33-1/1/1/34)# channel-group 1 mode active
OS10(conf-range-eth1/1/33-1/1/1/34)#

8. Exit the interface and configuration back to exec mode with the command end:

OS10(conf-range-eth1/1/33-1/1/1/34)# end
OS10#

9. On SWITCH #2 repeat the steps from SWITCH #1.
10. Verify the configuration changes made on the interface with the command show interface port channel summary:

OS10# show interface port-channel summary
LAG     Mode      Status    Uptime              Ports
1       L2        up        00:00:30            Eth 1/1/33 (Up)
                                                Eth 1/1/34 (Up)
OS10#

11. Show the interface port channel detailed information with show interface port channel 1 command:

OS10# show interface port-channel 1
Port-channel 1 is up, line protocol is up
Address is 0c:d3:b9:6e:00:51, Current address is 0c:d3:b9:6e:00:51
Interface index is 125
Internet address is not set
Mode of IPv4 Address Assignment: not set
Interface IPv6 oper status: Disabled
MTU 1532 bytes, IP MTU 1500 bytes
LineSpeed 50G
Minimum number of links to bring Port-channel up is 1
Maximum active members that are allowed in the portchannel is 32
Members in this channel: Eth 1/1/33-1/1/34
…

12. Verify the configuration changes made on the interface with the command show running-configuration interface Ethernet 1/1/33:

OS10# show running-configuration interface ethernet 1/1/33
!
interface ethernet1/1/33
 no shutdown
 channel-group 1 mode active
 no switchport
 flowcontrol receive off
OS10#

13. Verify the port channel configuration with the command show running-configuration interface port channel 1:

OS10# show running-configuration interface port-channel 1
!
interface port-channel1
 no shutdown
 switchport access vlan 1
OS10# Switch #1
show interface port-channel summary
Switch #2
show interface port-channel summary

14. To save the configuration changes, use the command write memory.

OS10# write memory
OS10#
