Why does my Cisco switch shut down after reboot?
If the port goes into shutdown mode immediately after a reboot of the switch, the probable cause is the port security setting. If unicast flooding is enabled on that port, it can cause the port to shut down after a reboot. Cisco recommends that you disable the unicast flooding because it also ensure that no flooding occurs on the port once the MAC address limit is reached.
What does it mean when a Cisco switch is not connected?
This means it is currently not connected to anything, but it will connect if it has a good connection to another operational device. If you connect a good cable to two switch ports in the notconnect state, the link light must become green for both ports, and the port status must indicate connected. This means that the port is up as far as Layer 1 (L1) is concerned.

How to check trunking mode?
Check the trunking mode on each side of the link. Make sure both sides are in the same mode (both trunking with the same method: ISL or 802.1q, or both not trunking). If you turn the trunking mode to on (as opposed to auto or desirable) for one port and the other port has the trunking mode set to off, they are not able to communicate. Trunking changes the formatting of the packet. The ports need to be in agreement as to what format they use on the link or they do not understand each other.
Why does Blackwater receive a corrupted packet?
The reason for this error message is the receipt of a packet from the switch fabric, where the CRC value in the fabric header on that packet did not match the CRC value calculated by the Fabric Interface Controller (FIC) subblock of the Blackwater ASIC. This indicates that a corruption of the packet occurred within transfer, and Blackwater received the corrupted packet.
How to enable 10 Gigabit Ethernet on Catalyst 4510R?
On a Catalyst 4510R series switch, in order to enable both the 10-Gigabit Ethernet and the Gigabit Ethernet SFP uplink ports , there is an optional configuration. In order to enable the simultaneous use of 10-Gigabit Ethernet and the Gigabit Ethernet SFP interfaces, issue the hw-module uplink select all command. After you issue the command, re-boot the switch or else the output of the show interface status module module number command shows the uplink port as inactive.
Why does my Ethernet chip send an error message?
This error message is caused when a frame is transmitted, and the local buffer of the controller chip local buffer receives insufficient data. The data cannot be transferred to the chip fast enough to keep pace with output rate. Normally, such a condition is temporary, dependent upon transient peak loads within the system. The issue occurs when an excessive amount of traffic is processed by the Fast Ethernet interface. The error message is received when the traffic level reaches about 2.5 Mb. This traffic level constrain is due to hardware limitation. Because of this, a chance exists for the device connected to the catalyst switch to drop packets.
