GUID-Node-ID

The GUID-Node-ID SPL option allows the Net-Net ESD to examine ingress SIP requests for the Cisco-GUID header. If present, the header is transparently passed through the egress SIP message. The system generates a new value for Cisco-GUID if not present or the SPL option is set to replace-ucid.

You must set the value to a 48-bit node ID in the version 1 GUID defined by RFC 4122. You can enter the value in decimal or hexadecimal notation. The value must be prefixed with 0x when hexadecimal.
