This article will explain how to manually change the management IP address of TMG800/TMG3200/TMG7800 of the Linux host.  


NOTE: Only the eth0 network interface should be change, eth1 should stays at 172.31.1.2 because it is directly connected to the Tmedia base board.

This article will explain how to manually change the management IP address of TMG800/TMG3200/TMG7800 of the Linux host.

On TMG800 and TMG3200 units you can have up to four internal interfaces:

  • pre-2011:
    • TMG800 -> Management Interface: eth0, Internal Interface: eth1
    • TMG3200-> Management Interface: eth0, Internal Interface: eth1
  • 2011 and after:
    • TMG800 -> Management Interface: mgmt0, Internal Interface: vlan3, 1+1 interface#1: vlan710, 1+1 interface#2: vlan711
    • TMG3200-> Management Interface: mgmt0, Internal Interface: int0, 1+1 interface#1: vlan710, 1+1 interface#2: vlan711

NOTE 1: Only the eth0/mgmt0 network interface should be changed, int0/vlan3/eth1 should stay at 172.31.1.2 since it is directly connected to the Tmedia base board and 1+1 vlans are configured with the Host role (see Tmedia 1+1).

NOTE 2: The network 172.31.1.x (netmask 255.255.255.0) cannot be used for the management IP.


On TMG7800-CTRL servers, you have three internal interfaces:

  • pre-2011:
    • TMG7800-> Management Interface: eth0, Internal Interface#1: eth1, Internal Interface#2: eth2
  • 2011 and after:
    • TMG7800-> Management Interface: mgmt0, Internal Interface#1: eth0, Internal Interface#2: eth1

NOTE 1: Only the eth0/mgmt0 network interface should be changed. eth1/eth0 will use the default address for primary (172.16.0.1) or secondary (172.16.0.2). eth2/eth1 will use the default address for primary (172.18.0.1) or secondary (172.18.0.2). (see Tmedia 1+1).

NOTE 2: The networks 172.16.x.x and 172.18.x.x (netmask 255.255.0.0) cannot be used for the management Interface IP.


Switch from DHCP to static

Modify the mgmt0 (or eth0) configuration

   vi /etc/sysconfig/network-scripts/ifcfg-mgmt0

NOTE 1: you need to remove the line DHCP_HOSTNAME

NOTE 2: int0/vlan3/eth1 interface must remain 172.31.1.2

Example:
   DEVICE=mgmt0
   BOOTPROTO=static
   IPADDR=192.168.1.10
   NETMASK=255.255.255.0
   IPV6ADDR=
   IPV6PREFIX=
   IPV6_AUTOCONF=yes
   ONBOOT=yes

Add the default gateway address in the network configuration file

   vi /etc/sysconfig/network
Example:
   HOSTNAME=TB005376
   NETWORKING=yes
   GATEWAY=192.168.1.1

Modify the DHCP client configuration

NOTE:If you don't have a nameserver, remove it from the file, if you do set it to a valid one(DNS). 

   vi /etc/resolv.conf
Example of a DNS configuration file without DNS server:
   ; generated by /sbin/dhclient-script


Example of a DNS configuration file containing a DNS server (in theory the dns server should configure itself properly):
   ; generated by /sbin/dhclient-script
   nameserver 4.2.2.2

Restart the network interfaces

   /etc/init.d/network restart

Switch from static to DHCP

Modify the mgmt0 (or eth0) configuration

   vi /etc/sysconfig/network-scripts/ifcfg-mgmt0

NOTE 1: you need to remove the IPADDR and NETMASK lines

NOTE 2: int0/vlan3/eth1 interface must remain static at 172.31.1.2

Example:
   DEVICE=mgmt0
   BOOTPROTO=dhcp
   IPV6ADDR=
   IPV6PREFIX=
   IPV6_AUTOCONF=yes
   ONBOOT=yes
   DHCP_HOSTNAME=TB005376

Remove the default gateway address in the network configuration file

   vi /etc/sysconfig/network
Example:
   HOSTNAME=TB005376
   NETWORKING=yes

Modify the dhcp client configuration

NOTE:If you don't have a nameserver, remove it from the file, if you do set it to a valid one(DNS). 

   vi /etc/resolv.conf
Example of a DNS configuration file without DNS server:
   ; generated by /sbin/dhclient-script


Example of a DNS configuration file containing a DNS server (in theory the dns server should configure itself properly):
   ; generated by /sbin/dhclient-script
