Configuring the GbE Interconnect Switch using the Web-based Interface
2. In the From and To fields, select the range of ports to be included in the settings.
3. In the PVID field, type the PVID. This tuning variable allows for subnetworks that are
expected to lose a large number of packets. The PVID is used by the port to tag outgoing,
untagged packets and to make filtering decisions about incoming packets. If the port is
specified as tagging, and an untagged packet is forwarded to the port for transmission, the
port will add an 802.1Q tag using the PVID to write the VID in the tag. When the packet
arrives at its destination, the receiving device uses the PVID to make VLAN forwarding
decisions. If the port receives a packet, and ingress filtering is enabled, the port compares
the VID of the incoming packet to its PVID. If the two are unequal, the port drops the
packet. If the two are equal, the port receives the packet.
4. In the Ingress Filter field, select Off or On to specify that the port checks the VID of
incoming packets against its VID or PVID. If the two are equal, the port receives the
packet. It the two are unequal, the port drops the packet. This setting is used to limit
traffic to a single VLAN.
5. In the GVRP field, select Off or On to enable or disable GARP VLAN Registration
Protocol.
6. Click Apply after making changes to the settings.
IMPORTANT: To save the configuration settings permanently, you must enter them into NVRAM using
the Save Changes option on the Maintenance menu. Refer to the section, “Saving Changes,” earlier in
this chapter.
Configuring Bandwidth
The GbE Interconnect Switch allows you to set a bandwidth limitation that restricts the
ingress (receiving) and egress (transmitting) packet rate for each port. If the packet rate
exceeds the allowed bandwidth rate, the excess packets will be dropped.
Bandwidth is configured in 1 to 127 units. Each unit is 117,481 bytes per second (around 0.94
Mb/s) for ports 1-24 and 939,850 bytes (about 7.52 Mb/s) for optional ports.
