Management
The switch can support up to two concurrent SSH client sessions.
9328 If the host IP address or the router IP interface used for management is in a zero subnet (for
example, 10.0.x.x/16), ARPs will resolve, and the host will be unable to ping devices within the subnet.
9367 ICMP packets containing the record route or timestamp options will not be forwarded by the
device.
11539 It is highly recommended that DAI (dynamic ARP inspection) be configured on edge ports only,
due to the potential for the DHCP snooping database to become out of sync during a system reset.
11593 Setting the SNMP community context to default via the “set snmp community xxx context
default” command could cause loss of SNMP management contact. In order to set a configured context
back to the default (NULL) context, enter a hyphen as the value of the context parameter. For example,
use the following command: “set snmp community abcde context ”.
12329 You cannot set port advertise speeds of 10t, 10tfd, 100tx, and 100txfd on combo ports.
12737 When initiating a telnet session from the console of the device to another device, the telnet
session will occasionally fail with the following error message: “telnet: Unable to connect to remote
host: Connection timed out”. Executing the command a second time will succeed.
13709 Auto-negotiation is required for MGBIC-LC01 link.
13972 Link Traps will only be sent to a maximum of three SNMPv3 notification targets.
14129 Disabling flow control while the system is under load may cause ports to stop forwarding. If it is
desired to have flow control disabled, it is recommended that the switch be preconfigured.
WebView (Web-based Management)
Configuration information for LAGs configured via WebView will not be reflected correctly when viewed
via the CLI.
RMON
When packets are transmitted outbound, they are counted under packet sizes 64 -1518 in RMON stats
but not total Packets or Octets.
Enabling RMON capture on an interface will cause packets to be duplicated on the interface while the
functionality is enabled.
Only RMON offset values of 1 through 1518 are supported.
RMON automatically creates entries for stats using indexes associated with each port. If any of the
automatically created indexes are cleared and then associated with a new entry with an index less than
450, the new entries will not be persistent. Upon resetting the device, RMON will automatically create
entries for each port using the initial default indexes. To avoid this situation, always use an index of 450
or greater when creating new entries.
Port counters and RMON counters may display differing values.
Packets greater than 1518 will not be counted by the IfInErrors MIB.
sFlow
14061 sFlow can create varying degrees of CPU utilization depending on the number of samplers,
sampling rate, pollers, and sampling interval. High CPU utilization can be mitigated by reducing
samplers and pollers, or increasing sampling rate and interval. Since traffic is switched in hardware,
CPU utilization should not affect switch performance. However, it may slow management response.
12004 sFlow does not sample with frame rates less than 1024fps.
