Introduction to the BayStack 410-24T Switch

MultiLink Trunking

The MultiLink Trunking feature allows you to group multiple ports (up to four) together when forming a link to another switch or server, thus increasing aggregate throughput of the interconnection between two devices (up to 800 Mb/s in full-duplexmode when an optional 100BASE-T MDA is installed). BayStack 410-24T switches can be configured with up to six MultiLink Trunks. The trunk members can be configured within a single unit in the stack or distributed between any of the units within the stack configuration (distributed trunking).

For more information about the MultiLink Trunking feature, see “MultiLink Trunks” on page 1-63.

IEEE 802.1Q VLANs

BayStack 410-24T switches support up to 64 port-based VLANs with IEEE 802.1Q tagging available per port.

When a switch port is configured to be a member of a VLAN, it is added to a group of ports (workgroup) that belong to one broadcast domain. You can assign different ports (and therefore the devices attached to these ports) to different broadcast domains.

This feature allows network flexibility because you can reassign VLANs to accommodate network moves, additions, and changes, eliminating the need to change physical cabling.

For more information about 802.1Q VLANs, see “IEEE 802.1Q VLAN

Workgroups” on page 1-38.

Port Mirroring

The port mirroring feature (sometimes referred to as conversation steering) allows a user to designate a single switch port as a traffic monitor for up to two specified ports or two media access control (MAC) addresses.

You can specify Port-Basedmonitoring, where all traffic on specified ports is monitored, or Address-Basedmonitoring, where traffic between specified MAC addresses is monitored.
