    When connecting to a non-point-to-point link, a port is incapable of rapid state transition. You can configure the link type as point-to-point for a port that works in full duplex mode. H3C recommends that you use the default setting to let the device automatically detect the port link type.

    If the physical link to which the port connects is not a point-to-point link but you set it to be one, your configuration may bring a temporary loop. Related commands: display stp. Examples # Configure the link connecting GigabitEthernet 1/0/1 as a point-to-point link. <Sysname>...

  • Page 82: Stp Timer Hello

    H3C does not recommend you to set the hello time with this command. Instead, you can specify the network diameter of the switched network by using the stp bridge-diameter command and let spanning tree protocols automatically calculate optimal settings of the hello timer.

  • Page 84: Stp Transmit-Limit

    In a stable network, this kind of spanning tree calculation may occur because the upstream device is busy. You can avoid such unwanted spanning tree calculations by lengthening the timeout time, saving the network resources. H3C recommends you to set the timeout factor to 5, 6, or 7 for a stable network. Related commands: stp timer hello.

    Packets that do not match any permit statements or that match a deny statement. When receiving • such a packet, DCC either sends it out without resetting the idle-timeout timer if a link is present, or drops it without originating calls for link setup if no link is present. For DCC to send packets normally, you must configure a dial ACL and associate it with the concerned dialup interface (dialer interface) by using the dialer-group command.
  • Page 131 The physical interfaces in C-DCC and Resource-Shared DCC do not use individual network addresses. Instead, they use the addresses of the corresponding dialer interfaces. In both C-DCC and RS-DCC, physical interfaces use the network addresses of their associated dialer interface rather than being assigned separate addresses.
