在接口上开启DHCP Client功能后,设备可以通过DHCP Server获取IP地址等配置参数。 如果DHCP Server为接口分配的IP地址与设备上其他接口的IP地址在同一网段,则该接口不会使用该IP地址,且不再向DHCP Server重新申请IP地址。如果需要重新申请IP地址,可以先在接口上执行命令shutdown,然后执行命令undo shutdown;或者先执行命令...

} 或者,在/etc/sysconfig/network-scripts/ifcfg-ens37加入"DHCPRELEASE=yes"。 当运行ip link set ens37 down的时候就会发出dhcprelase报文,查看/etc/sysconfig/network-scripts/ifdown-ens37脚本中实际上是调用dhclient命令,用下面这个命令应该也可以。 # 释放ip$ /sbin/dhclient -r ens37# 停掉网卡$ iplinkse...

From the NTT DHCPv6 server, my DHCPv6 Client has been assigned a /56 PD prefix with the following lifetimes: T1: 7200 T2: 10800 Preferred Lifetime: 12600 Valid Lifetime: 14400 The problem manifests itself at specific intervals — typically at the the 8-hour marks. Just when NTT's DHCPv6...
Link Layer optionsThe following sections describe the DHCP options that affect operation of the data link layer on a per-interface basis.Trailer EncapsulationThis option specifies whether the client negotiates the use of trailers, as described in RFC 893, when using the Address Resolution Protocol ...
This option is sent by the DHCPv4 server to the DHCPv4 client in a DHCPOFFER or a DHCPACK message. It has no effect on subsequent options in that message or on the DHCPREQUEST message sent by the client to the server. This option is used to set the default route metric (as sp...
