Configuring the GbE Interconnect Switch using the Web-based Interface
6. In the Priority (0–255) field, type a port priority from 0 to 255. The lower the priority,
the greater the probability that the port will be chosen as the root port.
7. In the ByPass field, select Yes or No. The bypass sets the forward delay timer to zero,
thus bypassing the waiting time before the listening state. (This procedure is also known
as fast forward.)
8. 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 Static (Destination Address) Filtering Table
The switch module uses a filtering database to segment the network and control
communications between segments. It can also filter packets off the network for intrusion
control. Static filtering entries can be made by MAC address.
Each port on the switch module is a unique collision domain. The switch module filters
(discards) packets whose destination lies on the same port as where it originated. This keeps
local packets from disrupting communications on other parts of the network.
For intrusion control, whenever an interconnect switch encounters a packet originating from
or destined to a MAC address entered into the filter table, the interconnect switch will discard
the packet.
Some filtering is done automatically by the switch module, including:
•
•
•
Dynamic filtering, which is automatic learning and aging of MAC addresses and their
location on the network. Filtering occurs to keep local traffic confined to its segment.
Filtering done by the Spanning Tree Protocol that can filter packets based on topology,
making sure that the signal loops do not occur.
Filtering done for VLAN integrity. Packets from a member of a VLAN destined for a
device on another VLAN will be filtered.
Some filtering requires the manual entry of information into a filtering table. This includes
MAC address filtering, which is the manual entry of specific MAC addresses to be filtered
from the network. Packets sent from one manually entered MAC address can be filtered from
the network. The entry may be specified as source, destination, or both.
