Description

Q: What will be the order and number of Link Aggregation Channels on NetScaler VPX, when creating Link Aggregation Channels on NetScaler SDX SVM in the following order?

  1. LA/3:10/1,10/2  
  2. LA/2:10/3,10/4  
A: On NetScaler VPX, the order and number of LA channels will be as follows:
  1. LA/1: 10/3,10/4 
  2. LA/2:10/1,10/2
The reason being is when you add the channel from SVM level on to the VPX, the VPX reboots and if it is the only channel on that VPX then it will show up as LA/1. If you have more than one LA/x channels bound to VPX, then the first unused ID will be picked and will reflect in LA/x as shown above.

When you run the show interface command you will see the following output:

7)      Interface LA/1 (802.3ad Link Aggregate) #7
        flags=0x41004000 <ENABLED, DOWN, AGGREGATE, down, HAMON, 802.1q>
