4.4 Configuring the Internal Bridge
Configuring Fast Ethernet Bridge
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.
