Correct, Everything is 100M in a Switched Enviroment.

Are we talking fully loaded with Analog calls or Analog calls and HDLC
calls? Here is what I'm actually seeing right now on this wire I have
approx 85 Max's and 4 fully loaded TNT's running into 2 interfaces on a
7206.
FastEthernet5/0 is up, line protocol is up
Hardware is DEC21140, address is 0060.7057.9c28 (bia 0060.7057.9c28)
Description: Ascend Ethernet, yea, ALL OF THEM.
Internet address is 10.11.64.2/24
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 31/255
Encapsulation ARPA, loopback not set, keepalive set (10 sec), fdx,
100BaseTX/FX
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of "show interface" counters never
Queueing strategy: fifo
Output queue 0/40, 11628 drops; input queue 1/75, 1487 drops
5 minute input rate 3542000 bits/sec, 4815 packets/sec
5 minute output rate 12335000 bits/sec, 2351 packets/sec
1605450923 packets input, 1801007490 bytes, 7 no buffer
Received 45736304 broadcasts, 0 runts, 0 giants
3 input errors, 3 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
0 watchdog, 0 multicast
3 input packets with dribble condition detected
1163750319 packets output, 3810760420 bytes, 96228 underruns
96228 output errors, 0 collisions, 150 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out
So thats what 3MB? I should be fine.

Shouldn't be a bottleneck, At least I hope not :)
