4. In the Key ID field, enter the key ID, from 1 through 65534.
5. In the Key Value field, enter any string up to 32 characters for the authentication
key value.
This key must match the key configured on the neighbor for which you specify
this key ID.
6. To define this key as a trusted key, check the Trusted Key box.
The Wireless Edge Services zl Module considers a neighbor that uses this key
to be a trusted source. Manually create a symmetric trusted key when you know
a neighbor’s public key, but cannot guarantee that the module can automatically
obtain that key securely from the neighbor.
7. Click the OK button. The new key is now listed in the section of the Special
Features > Secure NTP > Symmetric Keys screen.
Configuring NTP Neighbors
The Wireless Edge Services zl Module receives the time from NTP resources, or
neighbors. You can define a neighbor in one of two ways:
■ A peer—The module and the neighbor can both send time requests and
responses to each other. The two synchronize with each other.
■ A server—The module acts as a client to the neighbor. It sends time requests to
the neighbor and synchronizes to it. (The neighbor does not synchronize with
the module.)
