F3215-HP Load Balancing Module Network Management Command Reference-6PW101

241
trans-delay seconds: Sets the transmission delay interval in seconds, in the range of 1 to 3600. The
default is 1.
dead seconds: Sets the dead interval in seconds, in the range of 1 to 32768. The default is 40. It must
be identical to that on the virtual link neighbor. The dead interval is at least four times the hello interval.
md5: Enables MD5 authentication.
hmac-md5: Enables HMAC-MD5 authentication.
simple: Enables simple authentication.
key-id: Specifies the key ID for MD5 or HMAC-MD5 authentication, in the range of 1 to 255.
cipher: Sets a ciphertext password.
plain: Sets a plaintext password.
password: Specifies a password. In simple authentication mode, a plaintext password is a case-sensitive
string of 1 to 8 characters, and a ciphertext password is a case-sensitive string of 1 to 41 characters. In
MD5/HMAC-MD5 authentication mode, a plaintext password is a case-sensitive string of 1 to 16
characters, and a ciphertext password is a case-sensitive string of 1 to 53 characters.
Usage guidelines
As defined in RFC 2328, all non-backbone areas must maintain connectivity to the backbone. You can
use the vlink-peer command to configure a virtual link to connect an area to the backbone.
Considerations on parameters:
• The smaller the hello interval is, the faster the network converges and the more network resources
are consumed.
• A retransmission interval that is too small can cause unnecessary retransmissions. A large value is
appropriate for a low speed link.
• Specify an appropriate transmission delay with the trans-delay keyword.
The authentication mode at the non-backbone virtual link end follows the one at the backbone virtual link
end. The two authentication modes (MD5 or Simple) are independent, and you can specify neither of
them.
For secrecy, all keys and passwords, including keys and passwords configured in plain text, are saved in
cipher text.
If you do not provide the cipher or plain keyword, cipher applies to MD5/HMAC-MD5 authentication
mode and plain applies to simple authentication mode by default.
