! : Enabled Infinite Verify set ip default next-hop Limit the number of access hosts per port (number of MAC addresses) ---------- When a data frame is sent from the Access port, the switch strips the VLAN tag of the frame and then sends it out. S0 DCE 10 FastEthernet0/1 Commands When track1 is true , that is, 10.1.1.2 is reachable, the data of the PC accessing the 100 network is lost to 10.1.1.2 . If track 1 is hung, the next next-hop is switched. ? 100 i If the interface is trunk , set the trunk protocol type Switch(config-if)# switchport port-security aging static Do not advertise to any peer (well-known community) Do not export to next AS (well-known community) *>i The ETHERNET_SNAP frame can be used to transport multiple protocols. Therefore, SNAP can be seen as an extension that allows vendors to create their own Ethernet transport protocols. 8 8 8 8 2 : Reponse message, send all or part of its routing information, in a Response message Sender ( R2 ) saves basic configuration, such as BGP neighbor relationships * i100.0.2.0/24 After an ARP ACL ,ccnp switch labs free, if ARP packets are denyed by the ARP ACL , these packets are directly discarded, even in DHCP snooping. * 192.168.101.10, from 10.10.10.10, 00:12:46 ago, via Serial0/0 Route metric is 1, traffic share count is 1 Alternate port: Discard status. In addition to the root port and other ports to the root path, if the active root port fails, the replacement port becomes the root port, so the alternate port can be understood as an alternative to the root port. DAI supports on the access interface , trunk interface , EtherChannel interface , and private VLAN interface. In VTP server mode of SW3 is turned on VTP pruning after, Client of SW1 and SW2 are learning and also to open their VTP pruning . Metric When an activation of the Port-Security on the interface, MAC number of addresses has reached the maximum safe number of address configuration, and has received a new frame, and the source of this data frame MAC is not in these security addresses, then start punishment When the link between R1 and R3 fails, the same network will still have problems. Because R2 re-releases the locally configured static summary route into the Not used (set to all 0s ) The security address entry thus formed (which is SecureSticky ) will not be lost even if the interface is flipped. If wr saves the configuration and the command is written to config.text , the security address will not be lost even if the device is restarted. The maximum number of seconds allowed before the HOLDTime router must receive a keeplive or update message Configure the aging time type. If you select absolute , that is, absolute time, you need to use the aging time command to set the specific value of the aging time. After the command is pressed, all the security address entries built by the dynamically learned MAC will start. The aging time countdown. If it is the inactivity keyword, the countdown will only start when the dynamic security address entry is inactive (for example, if the host is offline or hanged).
