如果希望NetEngine 8000 M将报文分片后继续转发,则需要提前使能IPv4报文强制分片功能。 操作步骤 执行命令system-view,进入系统视图。 执行命令ipv4 mtu-fragment enable,使能MTU分片。 执行命令ipv4 force-fragment enable,使能IPv4报文强制分片功能。 执行命令commit,提交配置。

When I try to uncheck "Enable fragment outgoing IP4 packets" in menuconfig Code: Select all int err = sendto(sock, payload, len, 0, (struct sockaddr *)&dest_addr, sizeof(dest_addr)); if (err < 0) { ESP_LOGE(UDP_TAG, "Error occurred during sending: errno %d", errno); return ...
The reason that the overall length is increased by 60 is because three additional IPv4 headers were created, one for each fragment after the first fragment. The first fragment has an offset of 0, the length of this fragment is 1500; this includes 20 bytes for the slightly modified origina...

(6) (可选)设置封装后隧道报文的DF(Don’t Fragment,不分片)标志。 tunnel dfbit enable 缺省情况下,未设置隧道报文的不分片标志,即转发隧道报文时允许分片。 1.4 IPv4 over IPv4隧道显示和维护 1.4.1 显示IPv4 over IPv4隧道接口的信息 可在任意视图下执行以下命令: ...

Ping lets you specify the size of packets to use (the default is 32 bytes), how many to send, whether to record the route used, what Time-To-Live (TTL) value to use, whether or not to set the Don’t Fragment flag, and so on. Route.exe: Route Category The Route command-line...
