The switch is receiving BPDUs and populating the MAC address table, but not sending data.
Designated
Yes, By default port security is disabled on a Cisco switch. If it is enabled the default violation mode is shutdown with a maximum MAC address count of 1. Even if port-security is enabled it will not place a port into the shutdown state until either MAC address sticky or a static MAC address is configured on the port.
It is configured in VTP server mode. STP is automatically enabled. All switch ports are assigned to VLAN1.
The default value for network diameter on a STP configuration is 7 (seven). This value can be changed, using the command: Switch(config)#spanning-tree vlan 1 root primary diameter 5 This command changes the network diameter 50 5 (five) hops from end to end
Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.
STP stand for Spaning Tree Protocol. It's used to avoid the L2 loop in the network. many factor are belong to STP. such as Root Switch, BPDU, Root Port, Forward port, blocking port.
Based on the location of the root bridge, theother switches determine which of their ports has the lowest path cost to the root bridge. These ports are called root ports, and each switch (other than the current root bridge) must have one.
When in the switch none of the case's is true, the code at the default: is executed.
NOPE
yes switch work on ip address.
Either control switch is enabled on driver's door...or child switch on the insideof door (where it latches) is enabled
