---|---|---|---|---|---|---|
IP Addresses |
One, two, three, or four IPv4 or IPv6 addresses based on the number of interfaces you choose to use.
|
|||||
NTP Servers |
The IPv4 or IPv6 addresses or host names of the NTP servers you plan to use. If you want to enter multiple NTP servers, separate them with spaces. These should be the same NTP servers you use to synchronize devices, clients, and servers across your network.
The Crosswork Data Gateway host and virtual machine must be synchronized to an NTP server or the enrollment with Crosswork Cloud may not go through. |
|||||
DNS Servers |
The IPv4 or IPv6 addresses of the DNS servers you plan to use. If you want to enter multiple DNS servers, separate them with spaces. These should be the same DNS servers you use to resolve host names across your network. |
|||||
DNS Search Domain |
The search domain you want to use with the DNS servers (for example, cisco.com). You can only have one search domain. |
|||||
(Optional) Proxy Server |
URL of an optional management network proxy server. If your environment requires an HTTP or HTTPS proxy in order to access URLs on the public Internet, you must configure a proxy server for the Cisco Crosswork Data Gateway to connect to Crosswork Cloud. |
|||||
(Optional) Syslog Server |
Hostname, IPv4, or IPv6 address of an optional Syslog server. |
|||||
(Optional) Auditd Server |
Hostname, IPv4, or IPv6 address of an optional Auditd server. |
