Performance
■ J Series devices now support IDP and UTM functionality. Under heavy network
traffic in a few areas of functionality, such as NAT and IPsec VPN, performance
is still being improved to reach the high levels to which Juniper Networks is
consistently committed.
SNMP
■ On J Series devices, the SNMP NAT-related MIB is not supported in JUNOS Release
10.1.
System
■
On SRX650 devices, if one of the four Gigabit Ethernet ports (ge-0/0/0 through
ge-0/0/3) is linked up at 10 or 100 Mbps, it will not support jumbo frames.
Frames greater than 1500 bytes are dropped.
Unified Threat Management (UTM)
■ UTM requires 1 GB of memory. If your J2320, J2350, or J4350 device has only
512 MB of memory, you must upgrade the memory to 1 GB to run UTM.
VPNs
■ On SRX3400, SRX3600, SRX5600, and SRX5800 devices, the IPsec NAT-T tunnels
scaling and sustaining issues are as follows:
■ For a given private IP address, the NAT device should translate both 500
and 4500 private ports to same public IP address.
■ The total number of tunnels from a given public translated IP cannot exceed
1000 tunnels.
WLAN
■ The following are the maximum numbers of access points that can be configured
and managed from SRX Series devices:
■ SRX210—4 access points
■ SRX240—8 access points
■ SRX650—16 access points
NOTE: The number of licensed access points can exceed the maximum number of
supported access points. However, you can only configure and manage the maximum
number of access points.
