Junos 10.3 OS Release Notes
12
On J-SRX100, J-SRX210, and J-SRX240 devices, support for Layer LAG is added in both
standalone and cluster mode.
In cluster mode, the following CLI is now enabled to specify the number of aggregated
interfaces.
set chassis aggregated-devices ethernet device-count xxx
Support to add multiple links from each chassis to a reth interface is also available. In
the below example, 2 links from each chassis is added to reth3.
set interfaces ge-0/0/8 gigether-options redundant-parent reth3
set interfaces ge-0/0/9 gigether-options redundant-parent reth3
set interfaces ge-5/0/8 gigether-options redundant-parent reth3
set interfaces ge-5/0/9 gigether-options redundant-parent reth3
The following CLI is used for enabling LACP on reth interface:
set interfaces reth3 redundant-ether-options lacp active

Configuration

On J-SRX100, J-SRX210, and J-SRX240 devices, the current Junos OS default
configuration is inconsistent with the one in Secure Services Gateways, thus causing
problems when users migrate to J-SRX Series devices. As a workaround, users should
ensure the following steps are taken:
The interface should be configured as the Untrust port (with the DHCP
ge-0/0/0
client enabled).
The rest of the on-board ports should be bridged together, with a VLAN IFL and
DHCP server enabled (where applicable).
Default policies should allow trust->untrust traffic.
Default NAT rules should apply interface-nat for all trust->untrust traffic.
DNS/Wins parameters should be passed from server to client and, if not available,
users should preconfigure a DNS server (required for download of security packages).

Flow and Processing

On J-SRX Series devices, the factory default for the maximum number of backup
configurations allowed is five. Therefore, you can have one active configuration and a
maximum of five rollback configurations. Increasing this backup configuration number
will result in increased memory usage on disk and increased commit time.
To modify the factory defaults, use the following commands:
root@host# set system max-configurations-on-flash number
root@host# set system max-configuration-rollbacks number
where max-configurations-on-flash
configuration partition and
