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.
