fixed format, the router formats the AVP to use a fixed format of up to 15
characters consisting of all ASCII fields, as follows (the maximum number of
characters for each field is shown in brackets):
Fallback format for ATM interfaces:
<system name [4]> <slot [2]> <port [1]> <VPI [3]> <VCI [5]>
Fallback format for Ethernet interfaces:
<system name [4]> <slot [2]> <port [1]> <VLAN [8]>
Fallback format for serial interfaces:
<system name [4]> <slot [2]> <port [1]> <0 [8]>
Example The following command configures the fallback AVP 22 in fixed
format:
host1(config)#aaa tunnel calling-number-format-fallback fixed
For example, when you configure this fallback format on an E320 router for
an ATM interface on system name eastern, slot 14, adapter 1, port 2, VCI 3,
and VPI 4, the virtual router displays the format in ASCII as
'14' '2' '003' '00004'. The adapter number does not appear in this format.
fixed-adapter-embedded If you set up the router to generate the fallback AVP
22 in fixed–adapter-embedded format, the router formats the AVP to use a fixed
format of up to 15 characters consisting of all ASCII fields with a 1-byte slot field,
1-byte adapter field, and 1-byte port field:
Fallback format for ATM interfaces:
systemName (up to 4 bytes) slot (1 byte) adapter (1 byte)
port (1 byte) VPI (3 bytes) VCI (5 bytes)
Fallback format for Ethernet interfaces:
systemName (up to 4 bytes) slot (1 byte) adapter (1 byte)
port (1 byte) VLAN (8 bytes)
Fallback format for serial interfaces:
systemName (up to 4 bytes) slot (1 byte) adapter (1 byte)
port (1 byte) 0 (8 bytes)
For E120 routers and E320 routers, adapter is the number of the bay in
which the I/O adapter (IOA) resides, either 0 (representing the right IOA bay
on the E120 router and the upper IOA bay on the E320 router) or 1
(representing the left IOA bay on the E120 router or the lower IOA bay on
the E320 router). For ERX7xx models, ERX14xx models, and ERX310 routers,
which do not use IOAs, adapter is always shown as 0.
Slot numbers 0 through 16 are shown as ASCII characters in the 1-byte slot
field according to the following translation:
Slot ASCII
Number Character
0 0
1 1
