Trunk and Link Loop

When you create a trunk or link loop between the GbESM and another switch, packets might loop infinitely at line rate within the related links. When this problem occurs, the GbESM continuously displays the following messages at the console:

WARNING: packet_sent u: 0, dv_active: tx ring full

packet_sent dcnt=114, public1=110, vcnt=1025

Solution: Remove the loop to resolve this misconfiguration.

Trunk Traffic

Multicast, broadcast and DLF (Destination Lookup Failure, which are unknown destination MAC packets) traffic is sent to the lowest numbered port in the trunk. If this port is down, then the traffic is sent to the next lowest-numbered port. If the port that was down comes up again, the traffic is not re-hashed back to the recovered port.

Browser Based Interface

￿Some versions of Microsoft Internet Explorer version 6.x do not perform HTTP download efficiently. If you have one of these versions, HTTP software download might take much longer than expected (up to several minutes).

￿Web-browsers from different vendors may vary in their support of standard features. If you encounter problems using the BBI in a particular browser, a different browser may resolve the issue.

Strong Password Expiration

If you configure a Strong Password with automatic expiration, the password might not expire if the system date and time is not configured first. Use of a Network Time Protocol (NTP) server resolves this issue.

Solution: When you configure a strong password with automatic expiration, first configure the system time and date for the switch.
