Configuring Port Channel
Note If an EtherChannel (also known as port channel) is used between the upstream router or switch and the
SE for streaming real-time data, the EtherChannel load balance algorithms on the upstream switch or
router and the SE should be configured as “src-ip” and “dst-ip” respectively. Using this configuration
ensures session stickiness and general balanced load distribution based on clients’ IP addresses. Also,
distribute your client IP address space across multiple subnets so that the load balancing algorithm is
effective in spreading the traffic among multiple ports.
Typically, two Gigabit Ethernet ports on the motherboard (GigabitEthernet 1/0 and 2/0) can be bundled
for the management port channel, and four Gigabit Ethernet ports (GigabitEthernet 3/0, 4/0, 5/0, and 6/0)
on the network interface card (NIC) can be bundled for the traffic port channel.
To configure redundant dedicated management ports using the CLI, do the following:
Step 1 Configure two port channels., one with four Gigabit Ethernet ports (portchannel 1) and one with two
Gigabit Ethernet ports (portchannel 2) for application traffic and management traffic respectively.
SE(config)# interface GigabitEthernet 1/0
SE(config-if)# channel-group 2
SE(config-if)# exit
SE(config)# interface GigabitEthernet 2/0
SE(config-if)# channel-group 2
SE(config-if)# exit
SE(config)# interface GigabitEthernet 3/0
SE(config-if)# channel-group 1
SE(config-if)# exit
SE(config)# interface GigabitEthernet 4/0
SE(config-if)# channel-group 1
SE(config-if)# exit
SE(config)# interface GigabitEthernet 5/0
SE(config-if)# channel-group 1
SE(config-if)# exit
SE(config)# interface GigabitEthernet 6/0
SE(config-if)# channel-group 1
SE(config-if)# exit
Note The port channel carrying delivery traffic should always be configured as channel-group 1 and
set as the primary interface.
Step 2 Configure two different subnets for both port channels.
SE(config)# interface PortChannel 1
SE(config-if)# ip address 3.1.7.73 255.255.255.0
SE(config-if)# exit
SE(config)# interface PortChannel 2
SE(config-if)# ip address 3.1.8.200 255.255.255.0
SE(config-if)# exit
Step 3 Configure the delivery port channel as the primary interface.
SE(config)# primary-interface PortChannel 1
Step 4 Configure a default gateway for the delivery traffic.
SE(config)# ip default-gateway 3.1.7.1
Step 5 Set the load balancing algorithm to the destination IP address.
SE(config)# port-channel load-balance dst-ip
