Interfaces - Juniper JUNOS OS 10.4 - RELEASE NOTES Release Note

Limitations in Junos OS Release 10.4 for EX Series Switches
If you install a large configuration (more than 5 MB)—for example, if you install more
than four 40-port SFP+ line cards—in an EX8200 switch, the error message
"Configuration on the Switch is too large for JWeb to handle. Please use the CLI to
manipulate the configuration" is displayed in the Support Information page (Maintain
> Customer Support > Support Information) in the J-Web interface.
On EX8200 switches, if IS-IS is enabled on routed VLAN interfaces (RVIs), IS-IS
adjacency states go down and come up after a graceful Routing Engine switchover
(GRES).
Momentary loss of an inter-Routing Engine IPC message might trigger the alarm that
displays the message . There is no functionality
"Loss of communication with Backup RE"
affected.

Interfaces

EX Series switches do not support queued packet counters. Therefore, the queued
packet counter in the output of the command
show interfaces interface-name extensive
always displays a count of 0 and is never updated.
On EX3200 and EX4200 switches, when port mirroring is configured on any interface,
the mirrored packets leaving a tagged interface might contain an incorrect VLAN ID.
On EX8200 switches, port mirroring configuration is not supported on a Layer 3 interface
with the output configured to a VLAN.
On EX8200 switches, when an egress VLAN that belongs to a routed VLAN interface
(RVI) is configured as the input for a port mirroring analyzer, the analyzer incorrectly
appends a dot1q (802.1Q) header to the mirrored packets or does not mirror any packets
at all. As a workaround, configure a port mirroring analyzer with each port of the VLAN
as egress input.
The following interface counters are not supported on routed VLAN interfaces (RVIs):
local statistics, traffic statistics, and transit statistics.
EX Series switches do not support IPv6 interface statistics. Therefore, all values in the
output of the command always display a count
show snmp mib walk ipv6IfStatsTable
of 0.
On EX Series switches, when a firewall filter is applied on the loopback ( ) interface,
lo0
the switch stops generating local ARP requests for transit traffic.
The command might display double
show interfaces interface-name detail | extensive
counting of packets or bytes for the transit statistics and traffic statistics counters.
You can use the counter information displayed under the section of
Physical interface
the output.
