Cisco AS5x00 Case Study for Basic IP Modem Services

Section 3 Commissioning the Cisco AS5800 Hardware
Verifying Basic Setup
Step 4
From the Cisco 7206, verify that the DSI-Fast Ethernet interface and line protocol are up:
Router>show dsi
DSI-Fastethernet0/2/0 is up, line protocol is up
Hardware is DEC21140A, address is 0030.f2f5.1438 (bia 0030.f2f5.1438)
MTU 0 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 100Mb/s, 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, 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
. . .
Snip
The following example shows a dial shelf interconnection that changes state to up after the DSC card
reloads. Loss of DSIP Keepalive messages indicate no communication between the router shelf and dial
shelf. After DSIP Hello messages succeed, the Fast Ethernet DSI-Tx 0 and DSI-Rx 1 change their state
to up. Until these interfaces are up, the router shelf and dial shelf cannot communicate. No
debug
commands are used to create these console messages; however, the
terminal monitor
command is
required to watch them.

00:00:03: %LINK-3-UPDOWN: Interface Ethernet0, changed state to up

Note
In a production environment, verify that console logging is disabled. Enter the
show logging
command. If logging is enabled, the access server might intermittently
freeze up as soon as the console port gets overloaded with log messages. Enter the
no logging console
command.
The following messages appear on the console-terminal session after the DSC card is physically
removed from slot 12 and re-inserted. Approximately 120 seconds elapse before all these messages
appear.
