BLADE OS 5.1 Release Notes
BMD00098, December 2009 25
RADIUS with SSHv2
With RADIUS turned on, users might see a duplicate login prompt for SSHv2 clients, if the
RADIUS server is too slow to respond or if the RADIUS server is not available. In this case, users
must re-type the username and password to login.
RIP MIBs
Due to backward-compatibility issues, two Routing Information Protocol (RIP) MIBs are available
in BLADEOS:
ripCfg and rip2Cfg . Use the rip2Cfg MIB to configure RIPv1 and RIPv2
through SNMP.
BLADEOS does not support the standard RIPv2 MIB, as described in RFC 1724. Use the
rip2Cfg MIB to configure RIPv1 and RIPv2 through SNMP.
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.
