Chapter 8 Managing PNNI Nodes and PNNI Routing
Managing CUGs
If a prefix or address is not assigned to any CUG, it can still communicate with a CUG member only
when that member is configured to communicate with non-CUG members. This is described in
“Managing Access between a CUG Member and Non-Members or Members of Other CUGS,” which
appears later in this chapter.
To create a CUG or assign a new user to a CUG, use the following procedure.
Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher.
Step 2 To create a CUG or to add a prefix or address to an existing CUG, enter the addcug command using the
following format:
mgx8830a.1.PXM1.a > addcug <atm-address> <length> <plan> <cug-index> <aesa-ic>
[-callsbarred {none|incoming|outgoing}]
Table 8-20 defines the addcug command parameters and options.
Table 8-20 addcug/dspcug Command Parameters and Options
Parameter or Option Description
atm-address Replace this parameter with the NSAP or E.164 address or prefix of a local UNI
interface.
length If the prefix or address you are assigning to a CUG uses the NSAP format,
specify the address length in bits. A full AESA is 160 bits (20 bytes times 8 bits).
A shorter address length indicates an ATM address prefix, which assigns all
addresses with that prefix to the CUG you specify.
If the prefix or address you are assigning to a CUG uses the E.164 format, specify
the prefix or address length in digits.
plan If the prefix or address you are assigning to a CUG uses the NSAP format,
specify nsap.
If the prefix or address you are assigning to a CUG uses the E.164 format, specify
e164.
cug-index Enter a unique CUG Index number for this prefix or address. The range is 1 to
65535.
aesa-ic Replace this parameter with the 24-byte interlock code. You can use any 24-byte
number you want. The CUG specifications provide some recommendations for
this number. One option is to use the ATM address of a network node for the first
20 bytes and provide a unique 4-byte suffix. For example, if a particular
customer’s home network enters the ATM network at node xyz, you might use
the ATM address for node xyz as the prefix in the interlock code.
-callsbarred This option allows you to restrict access within the CUG. By default, each CUG
member can communicate with all other CUG members. To block calls from this
member to other CUG members, specify the -callsbarred outgoing option. To
block calls from other CUG members to this CUG member, specify the
-callsbarred incoming option.
Note You can use the cnfcug command to change CUG communications after
the CUG is assigned to a prefix or address.
