This article introduces the whole WAN configuration process with specific operation examples, and introduces the configuration principles and implementation steps. We also introduced POF and FR technologies.
Synchronous Serial Interface
1. This section describes the similarities between E1, T1, and T3.
Router # config t
Router (config) # controller e1 1
Router (config-controller) # channel-group 2 timeslots 1-10 speed 64
Router (config-controller) # channel-group 3 timeslots 11-13 speed 64 (SPEED value: 48 kbit/s, 56 kbit/s, 64 kbit/s-E1 default)
Router (config-controller) # cas-group 2 timeslots 1-10 type e & mfgb Router (config-controller) # service data (CAS false byte signaling, for T1 Transmission Group posts and clock)
Router (config-controller) # cas-group 3 timeslots 11-13 type e & mfgb
Service data
Router (config-controller) # clock source line primary/secondary | internal
(Reads the clock from the network or within the device for synchronization)
Router (config-controller) # framing sf/esf | crc4/nocrc4 (sf/esf-Router (config-controller) # T1, crc4/nocrc4-E1)
Router (config-controller) # linecode ami/b8zs/hdb3 (ami-T1, hdb3_e1)
Router (config-controller) # cablelength short 133/266 (optional, used if the cable length is less than 655 feet)
Router (config-controller) # cablelengh long gain26/-15 (optional, if the cable length is greater than 655 feet, the value is DB gain)
Router (config-controller) # line termination 75-ohm | 120-ohm (optional, meaning obvious)
Router (config-controller) # exit
Router (config) # interface s (where 1 is opposite to controller e1 1 and 2 is opposite to channel-group)
Router (config-interface) # physical-layer asynchronous (for port a/S)
Router (config-interface) # encapsulation ppp/hdlc (for all CISCO devices, HDCL is the default, but PPP is recommended)
Router (config-interface) # ppp authen chap
Router (config-interface) # ppp chap hostname wang
Router (config-interface) # ppp chap password wang
Router (config-interface) # compress stac/predictorhdlc only supports stc)
Router (config-interface) # crc 12 (optional, usually 16 bits)
Router (config-interface) # inver data (optional, used for non-B8ZS T1. If the DSU/CSU has been reversed, the ROUTER cannot be used)
Router (config-interface) # pulse-time 5 (for DRT pulse, optional)
Router (config-interface) # clock rate 56000 (a large number of optional values are used in DCE, depending on the specific situation. Generally, the high speed rate is used in short distances)
Router (config-interface) # transmit-clock internal 6
Router (config-interface) # scrmable)
Router (config-interface) # ip add 10.1.1.1 255.255.255.0
Router (config-interface) # no shut
Interface s1: 3 omitted
If it is an integrated T1 service module, commands must be different from other high-end modules)
SRouter (config-interface) # ervice-module t1 clock source internal/line (line by default)
Router (config-interface) # service-module t1 framing sf-esf
Wait. Basically, add service-module t1
2, POS, mainly introduces OC-3, STM-1 155M Interface
Router (config) # interface pos 3/1
Router (config) # pos framing-sdh
Router (config) # clock source
Router (config) # pos scramble-atm improves the conversion density of pyaload scrambling)
Router (config) # loop internale (start the environment test)
Router (config) # loop line Remote bad test)
Router (config) # no shut
Router (config) # ip add 10.1.1.1 255.255.255.0
Router (config) # aps working 1 working mode, where 1 is linked with the protection port value)
Router (config) # Or
Router (config) # aps prtect 1 192.168.1.1 255.255.0
Note: aps is an automatic protection switch. As the name suggests, aps can be set to work mode and protection mode)
Router (config) # crc 16/62
Router (config) # mtu 3000
3. There are enough frames in FR and frame relay, which is a little simpler.
Router (config) # interface s0/1
Router (config-interfcae) # encapsulation frame-relay cisco/ieft
Router (config-interfcae) # frame-relay lm-type ansi/cisco/q933a
Router (config-interfcae) # keepalive 15 (default value: 10 seconds)
Router (config-interfcae) # no shutdown
Sub-interface
Router (config-interfcae) # interface s0/1.1 point-to-point/multipoint (multi by default)
Router (config-interfcae) # frame-relay map ip 192.168.1.12 100 broadcast (ing the peer IP address to the local DLCI)
Router (config-interfcae) # frame-relay interfcae-dhci 100
Router (config-interfcae) # ip address 192.168.1.11 255.255.255.0
Another important configuration in FR is the integer and ing QOS.
4. Dial-up configuration (built-in MICA)
Router (config) # modem china mica
Router (config-pool) # modem-pool wang (MODEM pool name)
Router (config-pool) # pool-range (32-40) (line of MICA)
Router (config-pool) # alled-number 3333312 mxa-connection 3 find the modem pool by pulling in the number)
Router (config-pool) # exit
Line 32 40
Router (config-line) # transport input/all/output
Router (config-line) # autoselect ppp/slip
Router (config-line) # modem inout/dialin
Router (config-line) # modem prefrered none
Router (config-line) # speed 115200
Router (config-line) # flowcontrol hardware
Router (config-line) # stopbits 1
Router (config) # modem autoconf discovry
Router (config) # int xxx (too many posts, omitted)
The following are common MODEM diagnostics and maintenance commands:
Modem bad
Modem shutdown (active or disabled)
Modem recovery threshhold 10
Modem rrcovery-time 3 (points here)
Modem revovery action disable/download/none
Modem recovery maitenance action
Exit
