Accessing a partitioned NetScaler is the same as accessing a non-partitioned NetScaler: through the NetScaler IP (NSIP) address or any other management IP address. As a user, after you provide your valid logon credentials, you are taken to the partition to which you are bound. Any configurations that you create are saved to that partition. If you are associated with more than one partition, you are taken to the first partition with which you were associated. If you want to configure entities on one of your other partitions, you must explicitly switch to that partition.
After accessing the appropriate partition, configurations that you perform are saved to that partition and are specific to that partition.
To access a partitioned NetScaler appliance over HTTPS by using the SNIP (with management access enabled), make sure that each partition has the certificate of its partition administrator. Within the partition, the partition admin must do the following:
To configure in a NetScaler partition by using the command line interface
To configure in a NetScaler partition by using the configuration utility
With Link Aggregation Control Protocol (LACP), you can combine multiple ports into a single, high-speed link (also called a channel). An LACP-enabled appliance exchanges LACP Data Units (LACPDU) over the channel.
There are three LACP configuration modes that you can enable in the default partition of a NetScaler appliance:
Note: By default, the link aggregation is disabled in the default partition of the appliance.
LACP exchanges LACPDU between devices connected by an Ethernet link. These devices are typically referred as an actor or partner.
A LACPDU data unit contains the following parameters:
After exchanging LACPDUs, the actor and partner negotiate the settings and decide whether to add the ports to the aggregation.
To configure and verify LACP on a NetScaler appliance by using the command line
1. Enable LACP on each interface.
At the command prompt, type:
set interface <Interface_ID> -lacpMode PASSIVE -lacpKey 1
When you enable LACP on an interface, the channels are dynamically created. Additionally, when you enable LACP on an interface and set lacpKey to 1, the interface is automatically bound to channel LA/1.
Note: When you bind an interface to a channel, the channel parameters take precedence over the interface parameters, so the interface parameters are ignored. If a channel was created dynamically by LACP, you cannot perform add, bind, unbind, or remove operations on the channel. A channel dynamically created by LACP is automatically deleted when you disable LACP on all interfaces of the channel.
2. Set the system priority.
At the command prompt, type:
set lacp -sysPriority <Positive_Integer>
3. Verify that LACP is working as expected.
show interface <Interface_ID>
Note: In some versions of Cisco IOS, running the switchport trunk native vlan <VLAN_ID> command causes the Cisco switch to tag LACP PDUs. This causes the LACP channel between the Cisco switch and the NetScaler appliance to fail. However, this issue does not affect the static link aggregation channels configured in the above procedure.
