With this method, you configure the TFTP server IP address as the option value. In an IPv6 network, we recommend that you use the Cisco vendor-specific DHCPv6 information to pass the TFTP server IPv6 address For more information, see the documentation that Using option 150, gateways and phones discover the TFTP server IP address. We recommend that you enable IPv4 phones and gateways to use the DHCP custom option 150 to discover the TFTP server IP address. The remote cluster is manuallyĭefined, and Autoregistration should not be enabled. The cluster is a remote cluster that is also acting as a Proxy TFTP server for remote clusters. For this scenario, the Remote Cluster TFTP is manually defined and rollbackĪutoregistration will not work in this scenario. The other clusters, and does not process calls. In this case, the cluster has no relationship with The cluster can act as just a proxy TFTP cluster with no other purpose. Per remote cluster on the Primary TFTP server for redundancy.Ĭonsider the following scenarios that detail how Proxy TFTP can be used and the best practices for implementation. The recommended design for redundancy is 2 TFTP servers per cluster, and thus 2 IP addresses It is possible to configure any number of remote clusters on the primary TFTP server however, each remote cluster may contain Other remotely configured clusters such as Remote Cluster A, B, C, or N (any other remote clusters configured). When it receivesĪ request for TFTP from a device, the primary TFTP looks into its own local cache for the configuration file as well as any In the above illustration, a group of devices contacts the Primary TFTP server for their configuration files. More complicated multi-level hierarchies areįigure 1. The Proxy TFTP service functions as a single-level hierarchy is as illustrated. Multiple clusters or in any scenario where multiple clusters share the same DHCP TFTP option (150). The proxy TFTP can serve as a single TFTP reference for scenarios where a single subnet or VLAN contains phones from In multi-cluster systems, the proxy TFTP service is able provide TFTP files from multiple clusters via a single primary TFTP You should not create a peer relationship between nodesī and C. If the primary node A has a peer relationship with nodes B and C. ![]() When you configure peer relationships between the remote proxy TFTP servers in your network, keep the relationships hierarchical.Įnsure that the peer proxy TFTP servers on the remote clusters do not point to each other to avoid possible looping. You must create a peer relationship between each remote proxy TFTP server and the primary proxy TFTP server. The primary proxy TFTP server provides the configuration files for all phones and devices in the network. This is useful if you want to configure only one proxy TFTP server for many DHCP scopes, or have only one DHCP In a multiple cluster deployment, you can specify up to three remote proxy TFTP servers as peer clusters of the primary proxy Proxy TFTP server to TFTP Server Addresses sub-option type 1 in the DHCP scope. The second proxy TFTP server is added in option 150 for IPv4. In a single cluster deployment, the cluster must have at least one proxy TFTP server. Endpoints and Configuration Files for TFTP Deployments. ![]() ![]() Proxy TFTP server to use to get the configuration files. The DHCP scope specifies the IP address of the Your deployment and can service requests from endpoints on multiple clusters. A TFTP server can be installed in any cluster in Need, such as: dial plans, ringer files, and device configuration files. Use a proxy Trivial File Transfer Protocol (TFTP) server to provide the configuration files that endpoints in your network
