Configuring Fast Ethernet Bridge

Note

Note

RIC-155 includes a high-performance Fast Ethernet QoS bridge with VLAN tagging capabilities, MDI/MDIX automatic crossover and FDX flow control. Each port works at 10 Mbps or 100 Mbps, full duplex or half duplex mode (forced or autonegotiated).

To configure the Fast Ethernet bridge:

1.From the Configuration menu, select Bridge Configuration. The Bridge Configuration menu appears (see Figure 4-14).

2.From the Bridge Configuration menu, configure the following parameters:

Aging Time (a period of time from the moment when a node is disconnected from the network segment or becomes inactive and removal of the node address from the database.)

0 to 4080 seconds in 16 second increments

If aging time is set to 0 and address buffer has reached its maximum capability (1024 addresses) it stops storing new addresses.

Forwarding Mode (operation mode of the internal bridge)

Filter (frames are received with VLAN tag or untagged, the bridge learns the source address of the incoming frames, performs the bridging according to the MAC address only)

Filter Tagged (The bridge separates management traffic from the user traffic by the tags assigned to the frames. The switch operation complies with the relevant parts of IEEE 802.1Q.)

Whenever the Forwarding Mode is changed, the POS Port Egress (STM-1/OC3) and Tag Stripping (data and management Ethernet ports) are set to their default values and explained in Appendix B.

Statistics Counted (statistics collection mode)

OK only (RIC-155 counts the number of received good frames and the number of transmitted frames)

Failed only (RIC-155 counts the number of received bad frames with the number of encountered collisions)

Multicast & Broadcast Rate Limit (controls the traffic volume coming into the internal bridge): 128 kbps, 256 kbps, 512 kbps, 1 Mbps, 2 Mbps,

4 Mbps, 8 Mbps, No Limit.
