Managing ILMI
Disabling ILMI on a virtual port
If an attached device does not support ILMI, you will need to disable ILMI on the
virtual port. Note that if the remote device is an end-station then address
registration will not take place automatically and a static route will need to be
added for the attached device.
To disable ILMI on a virtual port, use the vport disable command.
Note: You must disable the virtual port before you can change or reset any virtual
port parameters. For more information about how to disable a virtual port, see
“Disabling a virtual port” on page 65.
Disabling ILMI polling on a virtual port
If an attached end-station does not support ILMI polling, the M770 ATM Switch will
not poll to ensure the integrity of the link. However, if the end-station does support
ILMI polling but is not responding to polls in time, the virtual port will not become
operational at all or be intermittent. Before the virtual port can become operational,
you will need to disable ILMI polling.
To disable ILMI polling on a virtual port, use the vport disable command.
Disabling ILMI multiple registration
Disables the registration of the same address via ILMI, on multiple ports.
To disable ILMI registration on multiple ports, use the vport
disable command.
Command: M15-155s8:/>vport disable <vport id> ilmi
Example: M15-155s8:/>vport disable 8.1.0 ilmi
Parameters: <vport id> The virtual port in the form <slot>.<port>.<virtualport
number>.
ilmi ILMI is a protocol used by a switch to learn about an
attached device.
Command: M15-155s8:/>vport disable <vport id> poll
Example: M15-155s8:/>vport disable 8.1.0 poll
Parameters: <vport id> The virtual port in the form <slot>.<port>.<virtual portnumber>.
poll ILMI polling is a mechanism used by the M770 ATM Switch to
ensure that the same end-station is still attached to it.
Since ILMI polling is an enhancement to ILMI, when ILMI is
disabled, polling is also disabled.
Command: M15-155s8:/>vport disable <vport id> ilmimultireg
Example: M15-155s8:/>vport disable 8.1.0 ilmimultireg
