Isis Circuit-Level - 3Com S7906E Command Reference Manual

password: Specifies a password. For simple authentication mode, the password must be plain text. For
md5 authentication mode, the password can be either plain text or ciphertext. A plain text password can
be a string of up to 16 characters, such as user918. A cipher password must be a string of 24
characters, such as _(TT8F]Y\5SQ=^Q`MAF4<1!!.
level-1: Sets the password for Level-1.
level-2: Sets the password for Level-2.
ip: Checks IP related fields in LSPs and SNPs.
osi: Checks OSI related fields in LSPs and SNPs.
This command is not available in loopback interface view.
Whether a password should use ip or osi is not affected by the actual network environment.
Description
Use the isis authentication-mode command to set the IS-IS authentication mode and password for an
interface.
Use the undo isis authentication-mode command to restore the default.
No neighbor relationship authentication is configured by default.
The password in the specified mode is inserted into all outgoing hello packets and is used for
authenticating the incoming hello packets. Only the authentication succeeds can the neighbor
relationship be formed.
Note that:
For two routers to become neighbors, the same authentication mode and password must be
specified at both ends.
If you set a password without specifying a level, the password applies to both Level-1 and Level-2,
If neither ip nor osi is specified, the OSI related fields in LSPs are checked.
The level-1 and level-2 keywords are available only on the VLAN interfaces of switches after IS-IS
is enabled on the interfaces with the isis enable command.
Related commands: area-authentication-mode, domain authentication-mode.
