Change Management IP's on 48000/IBM 2109-M48

Is it possible to change the default gateway for the CTP cards online without requiring a reboot or outage? We need to migrate over to a different network segment for management access.

If it can, I would be most grateful for some pointers on how.

Hi,

Modifying the ethernet management ports is an online operative. You can verify the current config with command ipaddrshow:

SWITCH:admin> ipaddrshow

CHASSIS
Ethernet IP Address: 10.64.160.133
Ethernet Subnetmask: 255.255.255.0

CP0
Ethernet IP Address: 10.64.160.118
Ethernet Subnetmask: 255.255.255.0
Host Name: cp0
Gateway IP Address: 10.64.160.1

CP1
Ethernet IP Address: 10.64.160.119
Ethernet Subnetmask: 255.255.255.0
Host Name: cp1
Gateway IP Address: 10.64.160.1

Backplane IP address of CP0 : 10.0.0.5
Backplane IP address of CP1 : 10.0.0.6
SWITCH:admin>

And modify each IP/mask/GW by using ipaddrset command:

SWITCH:admin> ipaddrset -chassis
Ethernet IP Address :
Ethernet Subnetmask :
SWITCH:admin> ipaddrset -cp 0
Host Name :
Ethernet IP Address :
Ethernet Subnetmask :
Gateway IP Address :
SWITCH:admin> ipaddrset -cp 1
Host Name :
Ethernet IP Address :
Ethernet Subnetmask :
Gateway IP Address :
SWITCH:admin>
