Adding and Deleting VLANs from the Port
To add VLANs to the port or delete VLANs from the port, from the VLAN
Port Configuration Menu, type o. Follow the instructions on the screen.
Enabling and Disabling Port Ingress Filtering
By default, a port will accept and forward tagged frames whether or not the port
is a member of a VLAN matching the VID of the tagged frame.
If ingress filtering is enabled, incoming tagged frames are forwarded only if the
port is a member of the VLAN matching the VID of the tagged frame. All other
frames are dropped and no addresses will be learned.
To enable or disable ingress filtering on the port, from the VLAN Port
Configuration Menu, type f to toggle port ingress filtering.
Configuring Port Receive Frame Type
By default, all ports on the IntraCore 6524 receive both 802.1Q tagged frames
and untagged frames. A port may be configured to receive only 802.1Q tagged
frames. This configuration is a necessary part of Inter-Switch Link (ISL)
configuration (see “Configuring Inter-Switch Links”).
If a port is configured to receive only tagged frames, any untagged frames
received by the port are dropped and the source address of the untagged frames
is not learned.
Incoming tagged frames are forwarded to the VLAN whose VID is included in
the tag header of the frame. See “Enabling and Disabling Port Ingress Filtering”
for more information about forwarding and filtering of received tagged frames.
To toggle the port between receiving all frames and receiving only tagged
frames, from the VLAN Port Configuration Menu, type t.
Configuring Inter-Switch Links
An inter-switch link (ISL) is a port that connects VLANs from two different
switches; it’s the means to share VLAN information between switches on a
network.
To configure a port as an ISL, you must do the following:
❑
Add the ISL port to each VLAN that is shared by the two switches.
This configures the port to share the VLAN traffic between the two
switches.
