flash card from the switch while the Fault LED on the front panel is on. Wait for the Fault LED

to turn off before removing the card.(4253)

 LACP priority value and the event log. A change to a switch’s LACP priority value is

registered in the event log with a message that reflects the current status of LACP, rather

than the change to the priority value. The log message is either “lacp:enabled” or

“lacp:disabled.” (3345)

 MAC address-based VLANs and static trunks. The documentation states that the ports of a

MAC address-based VLAN form a community and that the assignment of a MAC address to

one port in a VLAN is equivalent to assigning it to all ports. This is true except in the case

where the ports of a MAC address-based VLAN encompass a static port trunk, in which case

the same MAC addresses must be assigned to all the ports in the trunk. (3249)

 File upload or download. The switch’s response to management instructions may be slow

when you upload or download files to the file system.

 Reserved multicast traffic and port mirroring. The destination port of a port mirror may

transmit duplicates of some reserved multicast traffic, such as STP BPDUs and other control

packets. The duplication results from the destination mirror port transmitting both the

reserved multicast traffic it receives from flooded multicast traffic and the same multicast

traffic from the mirrored ports. (3055)

 Fiber optic port configuration display. The Auto-Negotiation, speed, and duplex mode settings

in the menus interface for ports 23 and 24 on the AT-9424T/GB and AT-9424T/SP switches

always reflect the settings of the corresponding twisted pair ports 23R and 24R. They do not

reflect the current settings of an active GBIC or SFP fiber optic port. (3047)

 GVRP compatibility. To avoid compatibility issues with GVRP and other switches. set the

GVRP Join Timer to 60 and the Leave Timer to 120.

 Port configuration. The speed, duplex mode, and MDI/MDIX settings of a 10/100/1000Base-T

twisted pair port are changed as a unit if multiple ports are configured simultaneously. The

settings of the lowest numbered port are automatically copied to the other ports. For

example, if you configure ports 1 to 4 simultaneously and change the MDI/MDIX setting, the

speed and duplex mode settings of port 1, along with the new MDI/MDIX setting, are copied

to ports 2 to 4. (1262)

 Jumbo frames loss. Frame loss on oversubscribed ports will be greater for jumbo frames

(1522 bytes or larger) than for regular frames, as illustrated here:(1412, 2783, 2792)

Regular Traffic

64 byte size frames @ 100% wire-speed = 1,488,100 packets per second (pps):

TX Port 1 (1,488,100 pps) =>

=> Receiving (Rcv rate = 1,488,100 pps) Total Loss = 50% Port 1 / 50% Port 2

TX Port 2 (1,488,100 pps) =>

Jumbo Traffic

9000 byte size frames @ 100% wire-speed = 13,851 pps:

TX Port 1 (13,851 pps) =>

=> Receiving Total Loss (approx.) = 62.5% Port 1 / 62,5% Port 2

TX Port 2 (13,851 pps) =>

 .Xmodem downloads. The switch does not respond to echo requests or send or respond to

STP BPDU packets during an Xmodem download of system software. Also, echo request

responses are slowed when there is a TFTP transfer in progress and the echo requests are

received within the same port group as the TFTP server. (1663, 1582)
