d-of-Line Blocking

This section applies to the Switch 4226T, Switch 4250T and Switch 4228G only.

If the Head of Line blocking settings have been changed from the default QoS setting, under very heavy network loading, where servers transmit large numbers of consecutive frames to multiple clients (i.e. using large window sizes), it is possible that other data streams may be disrupted due to local frame buffer capacity becoming exhausted. This could affect other network applications and in extreme conditions could cause stacked units to reconfigure from stacked to individual units in an unpredictable way.

figuring Link Aggregations

When creating a manual aggregation between two systems, the ports in the aggregation must not be physically connected together until the aggregation has been correctly configured at both ends of the link. Failure to configure the aggregation at both ends before physically connecting the ports can result in a number of serious network issues such as lost packets and network loops.

When configuring a manual aggregation, all member ports can only be selected from the same unit. Automatic aggregations (using LACP) can include ports from different units in a stack. However, only member ports from a single unit in the stack will be selected for activation. Upon failure, or disabling LACP on the active links, ports members from a different unit will be automatically activated (if all

members on the current unit athus ensuring resilient connecti

Problems with the Management reIf a port is unable to transmit packets due to an incorrect duplex mismatch setting or flow control is keeping the port continually in a pause state, management packets from the Switch can back up in the egress buffers and causes the Switch to stop passing packets on any port. Correcting the duplex mismatch and turning off flow control will fix this problem.

When setting up a SLIP IP address and an IP address for the unit you must ensure that the assigned IP addresses are different.

If you use Netscape to manage your Switch you may experience problems when trying to change the user password.

3Com recommends that if you use Netscape and you need to change the password you do so via the CLI command. To do this from the Web interface Device View, use the System > Telnet > Connect operation to start a Telnet connection and then use the security device user modify CLI command.

If the error The previous command window is still active is displayed when using the Web interface, you must close that window before you can select another operation. You should then press Reload (Netscape) or Refresh (Internet Explorer) in your Web browser.

The Switch 4200 Web interface can only be accessed by one of the following Web browsers:

Known Incomp

reason for this is that during the network reconfiguration that will accompany the addition or removal of a unit, it is possible that momentary network loops will occur. When a lot of traffic is present these loops could take several minutes to resolve and in the worst case may result in the need to reset the stack to complete the resolution.

■ If the Switch receives an IS-IS packet that is tagged with a VLAN ID of 0, the packet is discarded. All other VLAN IDs are switched correctly.

■ If you select the Bridge > Link Aggregation > Modify > LACP State web interface operation for a Switch that does not have any ports available or suitable for link aggregation, a blank screen displays without an accompanying error message. You can close this screen in the normal way.

■ Some operating system or web browsers allow you to disable pop-ups. Please note that pop-ups must be enabled for some web operations to work.
