Release Notes for the Industrial Ethernet 2000 Switch, Cisco IOS Release 15.2(2)E
Important Notes
VLAN Y belongs to the same multicast group, the IP-option traffic received on an input VLAN
interface other than one in VLAN Y is sent on the trunk port in VLAN Y because the trunk port is
forwarding in VLAN Y, even though the port has no group membership in VLAN Y.

forwarding in VLAN Y, even though the port has no group membership in VLAN Y.
There is no workaround. (CSCdz42909).
•
For trunk ports or access ports configured with IEEE 802.1Q tagging, inconsistent statistics might
appear in the show interfaces counters privileged EXEC command output. Valid IEEE 802.1Q
frames of 64 to 66 bytes are correctly forwarded even though the port LED blinks amber, and the
frames are not counted on the interface statistics.

VLAN
•
If the number of VLANs times the number of trunk ports exceeds the recommended limit of 13,000,
the switch can fail.
the switch can fail.
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
•
When line rate traffic is passing through a dynamic port, and you enter the switchport access vlan
dynamic interface configuration command for a range of ports, the VLANs might not be assigned
correctly. One or more VLANs with a null ID appears in the MAC address table instead.

The workaround is to enter the switchport access vlan dynamic interface configuration command
separately on each port. (CSCsi26392)

When many VLANs are configured on the switch, high CPU utilization occurs when many links are
flapping at the same time.

IPv4 Static Routing Notes
Cisco IE 2000 supports IPv4 static routing in the LAN Base image. To access static routing commands,
you need to change the SDM template from the default template to lanbase-routing, followed by a switch
reload sequence.
