DHCP Configuration DHCP Configuration on a Non-Routing System The following procedure provides basic DHCP server functionality when the DHCP pool is associated with the systems host IP address. Neighbor virtual link routers must have the same password. Achtung: Verweit auf wichtige Informationen zum Schutz gegen Beschdigungen. This guarantees that the default behavior of a bridge is to not be part of an MST region. set system login username {readwrite|read-only} enable (All other parameters are optional.) Creates a policy profile for the phones and a policy rule that maps tagged frames on the user ports to that policy profile. If you want to change the default timeout value for a specific server or all servers, you must enter the set tacacs server command using the timeout parameter. FIPS mode can be cleared using the clear security profile command. . The port cost value may also be administratively assigned using the set spantree adminpathcost command.
