Cabletron Systems 7C04-R, 7C03 Tp Frames Forwarded, Tp Frames Filtered, Sr Frames Forwarded

Using the 7C0x SmartSwitch Hub View

•DIS (disabled) — the port has been disabled by management; no traffic can be received or forwarded on this port, including configuration information for the bridged topology.

•LIS (listening) — the port is not adding information to the filtering database; it is monitoring Bridge Protocol Data Unit (BPDU) traffic while preparing to move to the forwarding state.

•LRN (learning) — the filtering database is being created, or the Spanning Tree Algorithm is being executed because of a network topology change. The port is monitoring network traffic, learning network addresses.

•BLK (blocking) — the port is on-line, but filtering traffic from going across the 7C0x SmartSwitch from one network segment to another. Bridge topology information is still being forwarded.

•BRK (broken) — the physical interface has malfunctioned.

Tp Frames Forwarded

Displays the percentage of total frames received that were transparently forwarded across the selected interface.

Tp Frames Filtered

Displays the percentage of total frames received that were filtered at the selected interface.

Sr Frames Forwarded

Displays the rate at which source route frames are being forwarded across the selected interface, in a frames/second format. Note that this option is currently grayed out, as no Token Ring NIMs are yet available.

Bridge Port Number

Displays the index number assigned to each bridge port interface. Bridge ports are indexed from left to right by module, beginning with the module installed in slot 2; on each module, bridge port numbering follows the physical port indexing. For example, the port display illustration in Figure 2-9(page 2-13) contains eight bridge interfaces: the two interfaces on the FDDI module installed in slot 2 are bridge port numbers 1 and 2 (corresponding to physical ports 1 and 2); the six interfaces on the Fast Ethernet module installed in slot 3 are bridge ports 3 through 8 (corresponding to physical ports 1 through 6).

NOTE

You will note that some Ethernet modules display an upside-down port indexing, with the highest index numbers at the top of the module, and the lowest ones at the bottom; for these modules, the bridge port numbers will still follow the physical port indexing, with the higher bridge port numbers corresponding to the higher physical port indices.
