The packets are distributed between ports in a LAG according to Source-MAC &
Destination-MAC addresses. Three Least Significant Bits (LSB) of MAC source
address are logically XOR-ed with 3 LSBs of MAC Destination Address. This
scheme ensures enhanced load balancing of the traffic, sent out through the LAG
ports.
You can manually configure a LAG using the CLI or a Management application.
When initially created, the LAG will inherit all parameters from the Base (the 1st
configured) port. These include Admin State (enable/disable), VLAN ID, Tagging
Mode, Priority Level, STA Enable/Disable, Auto-Neg, Flow Control, Duplex and
Speed. Each parameter change of the LAG interface will change this parameter in all
ports in the LAG.
If a link has failed, traffic distribution continues on other ports in the LAG. The port
is still configured as a member in the LAG and resumes operation in case of link up.
If you manually remove the port from the LAG, the port will automatically become
disabled. You can then change any of the port’s configuration parameters.
To set up a LAG or show an existing LAG configuration see the

set/show

channel commands in the CLI Chapter.

VLANs

The P130 suports 62 VLANs out of 4K tagged /untagged VLANs [1…4079]. All
VLANs are fully IEEE 802.1Q compliant (VLANs [4080…4095] reserved for internal
use).
The P130 has Standard VLAN MIB support.

Multiple VLANs per Port

The P130 provides the ability to set multiple VLANs per port. The two available
Port Multi-VLAN binding modes are:

Bound to Configured

- the port supports all the VLANs configured in the

switch/stack. These may be either Port VLAN IDs (PVID) or VLANs that were
manually added to the switch.

Statically Bound

- the port supports VLANs manually configured on it.

QoS and Priority Support

The P130 supports end-to-end QoS and provides the following tools:

Queuing

- Four egress queues per port

Port Priority

- Transparent IEEE 802.1p and per port basis

Scheduling

- Weighted Round Robin
