Enable Load Balancing

About this task

The NPB application supports GTP tunnel ID based load balancing.

Enter the interface port-channel configuration mode.

Device# configure terminal
Device#(config)# interface port-channel 1
Device(config-if-po-1)#

Enable src-ip, dst-ip, protocol, src-l4-port, and dst-l4-port based load balancing.
```
Device(config-if-po-1)# load-balance src-dst-ip-l4port
```
Note
For tunnel ID based load balancing, go to step 3.
Enable src-ip, dst-ip, protocol, src-l4-port, dst-l4-port, and tunnel id based load balancing.
```
Device(config-if-po-1)# load-balance src-dst-ip-l4port-tid
```
Enable the following individual LAG hash masking options as required:
1. dst-ip
```
# load-balance dst-ip
```
2. dst-l4-port
```
# load-balance dst-l4-port
```
3. protocol
```
# load-balance protocol
```
4. src-ip
```
# load-balance src-ip
```
5. src-l4-port
```
# load-balance src-l4-port
```
6. tun-id (Tunnel ID based load balancing only)
```
# load-balance tun-id
```
