How many SVC calls can this X25 interface handle in the interface output?

Serial1/2 is up, line protocol is up

Hardware is CD2430 in sync mode

Description: Test

MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec, rely 255/255, load 1/255

Encapsulation X25, loopback not set

X.25 DCE, address <none>, state R1, modulo 8, timer 0

Defaults: idle VC timeout 0

cisco encapsulation

input/output window sizes 2/2, packet sizes 128/128

Timers: T10 60, T11 180, T12 60, T13 60

Channels: Incoming-only none, Two-way 1-1024, Outgoing-only none

RESTARTs 1/0 CALLs 0+8/2580+10/2590+0 DIAGs 0/0

LAPB DCE, state CONNECT, modulo 8, k 7, N1 12056, N2 20

T1 3000, T2 0, interface outage (partial T3) 0, T4 0

VS 0, VR 7, tx NR 7, Remote VR 0, Retransmissions 0

Queues: U/S frames 0, I frames 0, unack. 0, reTx 0

IFRAMEs 12720/12919 RNRs 0/0 REJs 0/0 SABM/Es 1/0 FRMRs 0/0 DISCs 0/0

Last input 00:00:01, output 00:00:01, output hang never

Last clearing of "show interface" counters never

Queueing strategy: fifo

Output queue 0/40, 0 drops; input queue 0/75, 0 drops

5 minute input rate 0 bits/sec, 0 packets/sec

5 minute output rate 0 bits/sec, 0 packets/sec

38748 packets input, 397658 bytes, 0 no buffer

Received 0 broadcasts, 0 runts, 0 giants, 0 throttles

0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

41842 packets output, 314727 bytes, 0 underruns

0 output errors, 0 collisions, 0 interface resets

0 output buffer failures, 0 output buffers swapped out

0 carrier transitions

DCD=up DSR=up DTR=up RTS=up CTS=up

Re: How many SVC calls can this X25 interface handle in the inte

4095 is the sum of pvcs, incoming svc, two-way svc, outgoing svc. You can split this total as you like better as long the other side is aware of the ranges.

Hop this helps, please rate post if it does!

Hello,

X.25 can support up to 4095 VCs. The range must be agreed with the service provider.

Hope this helps, please rate post if it does!

Re: How many SVC calls can this X25 interface handle in the inte

Thanks but what about SVC's..the config doesn't seem to indicate any limit on the number of incoming/outgoing SVC calls that can be made so can I assume that I have a mx of 4095. The interface on this router is directly connected to a 3rd party over a leased line with X25 encapsulation on the interface. This is not part of the public X25 network.

interface Serial1/2

description Test

bandwidth 64

no ip address

no ip directed-broadcast

encapsulation x25 dce

no ip mroute-cache

no cdp enable
