Intel® NetStructure™ 6000 Switch

C H A P T E R 5
Managing the Switch
VLAN routing configuration allows control of what VLAN IP frames
can be routed. For example, it is possible to specify that VLAN 3
cannot be used as the source when forwarding IP frames.
Note If IP routing is disabled for a VLAN, it only applies to
ingress or received IP frames. It is still possible for other
VLANs to route to the VLAN.
VLAN routing configuration can be used in environments where
VLANs exist, and those VLANs are given IP addresses for
management, but no routing is required. In this environment, IP
routing can be disabled for each VLAN.
Type vlan VID disable iproute to disable VLAN routing.
Caution
For more complex environments, access control lists
should be used to control IP routing. See IP Access
Control in this chapter.
Spanning Tree Protocol
The 6000 Switch adds an extra layer of functionality with the
introduction of multilayer Spanning Trees. The two types of
Spanning Tree models are:
• IEEE 802.1d Spanning Tree
The switch becomes a bridge for which Spanning Tree parameters
can be set. Every port, regardless of VLAN membership, is part of the
same Spanning Tree.
• Spanning Tree per VLAN
The switch supports IEEE 802.1s, a supplement to 802.1Q, that
provides for multiple instances of Spanning Tree to run on a switch
that has multiple VLANS. Each VLAN acts as a separate bridge or
Virtual Bridge which allows you to set the entire range of Spanning
Tree commands for that bridge and the bridge ports.This allows
traffic to pass that would otherwise be blocked.
To activate the Spanning Tree protocol
1 Type enable spantree in privileged mode.
2 Select which type of Spanning Tree to implement.
Type set spantree type stp to configure 802.1d Spanning Tree.
