Link Aggregation - IBM BladeCenter Installation And User Manual

To set an Ingress Filter, select the desired module and port(s) in the first two fields
and then use the Spacebar to toggle between Enabled and Disabled in the
Ingress Filter field.
An Ingress Filter enables the port to compare the VID tag of an incoming packet
with the both the VIDs and PVIDs of VLANs assigned to the port. If the VID tag of
an incoming port is different from either the VID or PVID assigned to the port, the
port filters (drops) the packet.
You can enable a port to dynamically become a member of a VLAN, enable or
disable GARP VLAN Registration Protocol (GVRP), where GARP is the Generic
Attribute Registration Protocol, on an individual port. To set GVRP, complete the
following steps:

GVRP is a GARP application that provides 802.1Q-compliant VLAN pruning and
dynamic VLAN creation on 802.1Q trunk ports. With GVRP, the switch can
exchange VLAN configuration information with other GVRP switches, prune
unnecessary broadcast and unknown unicast traffic, and dynamically create and
manage VLANs on switches connected through 802.1Q trunk ports. GVRP updates
dynamic VLAN registration entries and communicates the new VLAN information
across the network. This enables, among other things, stations to physically move
to other switch ports and keep their same VLAN settings, without having to
reconfigure VLAN settings on the switch.

Link Aggregation

The switch module supports Link Aggregation, or port trunking. Port trunks
(aggregated ports) can be used to increase the bandwidth of a network connection
or to ensure fault recovery.
You can configure up to two trunk connections (combining two to four ports into one
fat pipe) between any two BladeCenter switches or other Layer 2 switches.
However, before making any physical connections between devices, use the Link
Aggregation menus to specify the ports that will belong to the trunking group on
both switches.
When using a port trunk, note that:
v The ports used in a trunk must all be of the same speed (100 Mbps or 1000
v The ports that can be assigned to the same trunk have certain other restrictions,
v Each port can only be assigned to one trunk group, whether a static or dynamic
v The ports at both ends of a connection must be configured as trunk ports.
v All of the ports in a trunk have to be treated as a whole when moved from/to,
v The Spanning Tree Protocol (STP) will treat all the ports in a trunk as a whole.
v Enable the trunk before connecting any cable between the switches to avoid
v Disconnect all trunk port cables or disable the trunk ports before removing a port
