Load Sharing
See “Configuring Ports”
on page 79.
Load sharing allows you to increase bandwidth and resiliency by
using a group of ports to carry traffic in parallel between systems. The
switch’s sharing algorithm allows you to use multiple ports as a
single logical port.
For example, VLANs treat the load-sharing group as a single virtual
port.
Software Licensing - Router
License Keys
You can expand the feature set of your switch using a license key.
The keys are unique to the 480T routing switch and are not
transferable. Keys are stored in NVRAM and, once entered, persist
through reboots, software upgrades, and later reconfigurations.
In the firmware, routing protocol support is separated into two sets:
• Basic
•
Full Layer 3.
Basic is a subset of Full Layer 3.
Basic Functionality
Basic functionality requires no license key. It includes all switching
functions, as well as all available Layer 3 QoS, access list, and ESRP
functions.
Basic includes support for these Layer 3 routing functions:
• IP routing using RIP version 1, RIP version 2, or both
• IP routing between directly attached VLANs
• IP routing using static routes
