You can configure a port as an access port or trunk port or let the Dynamic Trunking Protocol DTP operate on a per-port basis to set the switchport mode by negotiating with the port on the other end of the link. Power over Ethernet PoE Enabled auto. When policing of the real-time power consumption is enabled, the switch takes action when a powered device consumes more power than the maximum amount allocated, also referred to as the cutoff-power value. Routed ports can be configured with a Layer 3 routing protocol. With a standard Layer 2 switch, ports in different VLANs have to exchange information through a router. If the physical cable is connected, you can still use the enable keyword to enable the port. Optional Displays the RPSs that are connected to each switch in the stack or to the specified switch. To configure a range of interfaces with the same parameters, follow these steps beginning in privileged EXEC mode:.
Somebody knows why if an Ethernet port is configured as mdix auto, this port must be I believe the cat is also affected by this bug.
MDI/MDI-X Status on Catalyst g. Hi. Cisco is looking for Network, Security, and Data Center IT professionals to help shape the future of.

Cisco Catalyst CX and CX support a maximum of six Displays the operational state of the auto-MDIX feature on the interface.
For information about using the software activation feature to install a software license for a specific feature set, see the Cisco IOS Software Activation document.
Note When you use the interface ranges with port channels, the first and last port-channel number must be active port channels.
Displays the interface speed and duplex mode configuration. If you configure auto-selectyou cannot configure the speed and duplex interface configuration commands. Switch config-if switchport autostate exclude. When STP is enabled and a port is reconfigured, the switch can take up to 30 seconds to check for loops.
The commands are collected and applied to the interface when you enter another interface command or enter end to return to privileged EXEC mode.
Automatic medium-dependent interface crossover (auto-MDIX) is. This chapter defines the types of interfaces on the Catalyst switch and When you enable auto-MDIX, you must also set the interface speed and duplex. The Catalyst E and E switches have two Gigabit Table shows the link states that result from auto-MDIX settings and.
With auto-MDIX enabled, you can use either type of cable to connect to other devices, and the interface automatically corrects for any incorrect cabling. Configuring a Range of Interfaces You can use the interface range global configuration command to configure multiple interfaces with the same configuration parameters.
It is always off for sent packets.
If the RPS still has power available, it can then provide power to the switches with lower priorities. If you do not specify a wattage, the switch pre-allocates the maximum value.
