• url - An alphanumeric string (maximum length 255 characters) in HTTP URL format. Default Configuration There is no redirect URL configured by default. Command Mode Global Configuration User Guidelines The switch will redirect HTTP and HTTPS packets for unauthenticated 802.1x clients to the redirect target using the configured URL with HTTP redirect code 302(Found) or 200 (OK). The url parameter consists of an HTTP URL with meta-characters. The meta-characters are substituted by the switch with information from the redirected host. A redirect URL is used in conjunction with a statically-configured ACL in authentication open mode. The ACL must contain a permit clause for access to the redirect target and any other services provided to unauthenticated hosts, such as DNS or DHCP. Other clauses restricting access to the network may be added as desired. The redirect URL (and the HTTP hijack) is only active if the host is unauthenticated. When authentication succeeds via 802.1X or MAB, the authentication server must send a dynamic ACL allowing access to the network. The dynamic ACL will replace the static ACL described in the preceding paragraph. The following meta characters may be configured in the URL string. The switch will substitute the listed information in the URL string. The size of the URL string with substitutions may not exceed 384 characters. • Host MAC address (\M) • Host IPv4 or IPv6 address (\H) • Switch port (ifIndex) (\P) • Switch IPv4 or IPv6 address (\I) • Original URL (\U) • Switch Manufacturer or Model (\O) Security Commands 994
