Cisco 7000 (CLAW) support
|
| 2 |
|
|
|
| 3 |
|
|
The c7000 module provides support for a channel attached Cisco 7xxx
|
| 4 |
|
|
family router on Linux/390. The parameters for the module are as follows:
|
| 5 |
|
|
|
| 6 |
|
|
base0=0xYYYY This parameter defines the base unit address of the
|
| 7 |
|
|
channel attached router.
|
| 8 |
|
|
|
| 9 |
|
|
lhost0=s1 This parameter defines the local host name and
|
| 10 |
|
|
must match the claw directive "host-name" field
|
| 11 |
|
|
(first string). The default value is "UTS".
|
| 12 |
|
|
|
| 13 |
|
|
uhost0=s2 This parameter defines the unit's name and must
|
| 14 |
|
|
match the claw directive "device-name" field
|
| 15 |
|
|
(second string). The default value is "C7011".
|
| 16 |
|
|
|
| 17 |
|
|
lappl0=s3 This parameter defines the local application name
|
| 18 |
|
|
and must match the claw directive "host-app" field
|
| 19 |
|
|
(third string). The default value is "TCPIP".
|
| 20 |
|
|
|
| 21 |
|
|
uappl0=s4 This parameter defines the unit application name and
|
| 22 |
|
|
must match the claw directive "device-app" field
|
| 23 |
|
|
(fourth string). The default value is "TCPIP".
|
| 24 |
|
|
|
| 25 |
|
|
dbg=x This parameter defines the message level. Higher
|
| 26 |
|
|
numbers will result in additional diagnostic messages.
|
| 27 |
|
|
The default value is 0.
|
| 28 |
|
|
|
| 29 |
|
|
noauto=z This parameter controls the automatic detection of
|
| 30 |
|
|
the unit base address (base0). When set to a non
|
| 31 |
|
|
zero value, automatic detection of unit base addresses
|
| 32 |
|
|
is not done. The default value is 0.
|
| 33 |
|
|
|
| 34 |
|
|
Note that the values coded in strings s1 - s4 are case sensitive.
|
| 35 |
|
|
|
| 36 |
|
|
For example, assume that the following claw directive has been coded in
|
| 37 |
|
|
the Cisco router:
|
| 38 |
|
|
|
| 39 |
|
|
claw 0100 6C 129.212.61.101 UTS C7011 TCPIP TCPIP
|
| 40 |
|
|
|
| 41 |
|
|
The module can be loaded using the following command:
|
| 42 |
|
|
|
| 43 |
|
|
insmod c7000 base0=0x336c lhost0="UTS" uhost0="C7011" lappl0="TCPIP" \
|
| 44 |
|
|
uappl0="TCPIP" dbg=0 noauto=1
|
| 45 |
|
|
|
| 46 |
|
|
Additional interfaces can be defined via parameters base1 - base3,
|
| 47 |
|
|
lhost1 - lhost3, lappl1 - lappl3, uhost1 - uhost3, uappl1 - uappl3.
|
| 48 |
|
|
The interfaces are named "ci0" - "ci3". After loading the module, the
|
| 49 |
|
|
ifconfig command is used to configure the interface. For example:
|
| 50 |
|
|
|
| 51 |
|
|
ifconfig ci0 129.212.61.101
|
| 52 |
|
|
ifconfig ci0 netmask 255.255.255.0 broadcast 129.212.61.0
|
| 53 |
|
|
ifconfig ci0
|
| 54 |
|
|
|
| 55 |
|
|
The route command is used to specify the router as the default route:
|
| 56 |
|
|
|
| 57 |
|
|
route add default gw 129.212.61.200
|
| 58 |
|
|
|
| 59 |
|
|
The interface can be automatically activated at boot time by following this
|
| 60 |
|
|
procedure:
|
| 61 |
|
|
|
| 62 |
|
|
1) Add the following two lines to file "/etc/conf.modules":
|
| 63 |
|
|
|
| 64 |
|
|
alias ci0 c7000
|
| 65 |
|
|
options c7000 base0=0xYYYY lhost0=s1 uhost0=s2 lappl0=s3 uappl0=s4
|
| 66 |
|
|
|
| 67 |
|
|
2) Edit file "/etc/sysconfig/network" as follows:
|
| 68 |
|
|
|
| 69 |
|
|
NETWORKING=yes
|
| 70 |
|
|
FORWARD_IPV4=no
|
| 71 |
|
|
HOSTNAME=your-hostname
|
| 72 |
|
|
GATEWAYDEV=ci0
|
| 73 |
|
|
GATEWAY=your-gateway-ip-address
|
| 74 |
|
|
|
| 75 |
|
|
Substitute your own host name and gateway IP address.
|
| 76 |
|
|
|
| 77 |
|
|
3) Create a file in directory "/etc/sysconfig/network-scripts" called
|
| 78 |
|
|
"ifcfg-ci0". The contents are as follows:
|
| 79 |
|
|
|
| 80 |
|
|
DEVICE=ci0
|
| 81 |
|
|
USERCTL=no
|
| 82 |
|
|
ONBOOT=yes
|
| 83 |
|
|
BOOTPROTO=none
|
| 84 |
|
|
BROADCAST=your-broadcast-ip-address
|
| 85 |
|
|
NETWORK=your-network-address
|
| 86 |
|
|
NETMASK=your-netmask
|
| 87 |
|
|
IPADDR=your-ip-address
|
| 88 |
|
|
|
| 89 |
|
|
Substitute your IP address, broadcast IP address, network address and
|
| 90 |
|
|
network mask.
|
| 91 |
|
|
|
| 92 |
|
|
4) chmod +x ifcfg-ci0
|
