Note subnet mask needs to be entered in hex! i.e. 255.255.255.0 == ff.ff.ff.00

Reboot is not needed, access to telnet will now work. Note, ssh is not supported.

Module 13 is disabled, let's enable and disable it (connected and isolated in IBM speak):-
ibm8265_01# set module 13 connected Slot 13:Module set ibm8265_01# ibm8265_01# set module 13 isolated Slot 13:Module set ibm8265_01#
Isolated means it can be swapped whilst the chassis is powered on. Slots 1 - 17 are for network modules, slots 18 & 19 are for power control modules. Note that slots 9 & 10 HAVE to be used for the CPSW module in single fabric mode, if a redundant CPSW module is fitted, it has to go in slots 11 & 12.
Port 17.1 is connected to a Fore / Marconi PCA200e 155MB/s pci card on a computer running Centos 6.5, seen below, atmsigd has been started but not ilmid, in the second example, ilmid has been started.

Changes are activated immediately they are made, but are not saved to nv ram so will be lost on a device reload. There are several save options, but save all does the lot in one go.
