LANE Shortcuts

Use the lane shortcuts command to display all or specific entries using LANE
shortcuts. You can also display any ATM addresses for which LANE shortcuts are
disallowed due to operational problems.

Syntax:

lane-shortcuts

all

entry

disallowed

all

Displays all LANE shortcuts.

Example:

lane all

LANE Shortcut Interface #: 1, ATM Network Interface #: 0

===========================================================

entry

Displays a LANE shortcut entry.

Example:

lane entry

LANE Shortcut Interface number [0]? 1

Enter IP address of next hop [0.0.0.0]? 5.5.5.1

Next Hop Addr: 5.5.5.1

RI Field:064001020203

disallowed

Displays all disallowed LANE shortcut entries.

Any ATM address listed in this display means that the NHRP LANE
Shortcut Interface received data from that ATM address. This is not allowed
since all NHRP LANE Shortcut Interface VCCs will be used only to transmit
data to a LEC at the other end. If the LEC attempts to send data over a
VCC set up by an NHRP LANE Shortcut Interface, then the VCC will be
brought down and no further LANE shortcuts will be set up to that LEC.

Once the condition which caused the NHRP LANE Shortcut Interface to
receive data has been corrected, then the device must be restarted in order
to allow that ATM address to be again used for NHRP LANE shortcuts.

Example:

lan dis

LAN Shortcut Interface #: 2, ATM Network Interface #: 0
