Specifications

•
License support to activate ports (MX104)—Starting with Junos OS Release 13.3,
license support has been extended for activating the ports on MX104 3D Universal
Edge Routers. MX104 routers have four built-in ports. By default, in the absence of any
valid licenses, all four built-in ports are deactivated. The upgrade license model with
the feature IDs is described in Table 1 on page 38.
Table 1: Port License Model for the MX104
FunctionalityFeature NameFeature ID
Ability to activate the first two built-in ports (xe-2/0/0 and
xe-2/0/1)
MX104 2X10G Port Activate (0 and 1)F1
Ability to activate the next two built-in ports (xe-2/0/2 and
xe-2/0/3)
MX104 2X10G Port Activate (2 and 3)F2
Both features are also provided in a single license key for ease of use. MX104 routers
do not support the graceful license expiry policy.
•
Enhanced load-balancing for MIC and MPC interfaces (MX Series) — Starting with
Junos OS Release 13.3, the following load-balancing solutions are supported on
aggregate Ethernet bundles to correct genuine traffic imbalance among the member
links:
•
Adaptive — Uses real-time feedback and control mechanism to monitor and manage
traffic imbalances.
•
Per-packet random spray — Randomly sprays the packets to the aggregate next
hops to ensure that the next hops are equally loaded, resulting in packet reordering.
The aggregated Ethernet load-balancing solutions are mutually exclusive. To configure,
use the adaptive or per-packet statement at the [edit interfaces aex
aggregated-ether-options load-balance] hierarchy level.
[See Example: Configuring Aggregated Ethernet Load Balancing.]
•
Support for configuring interface alias names—Starting in Junos OS Release 13.3, you
can configure a textual description of a logical unit on a physical interface to be the
alias of an interface name. Interface aliasing is supported only at the unit level. If you
configure an alias name, the alias name is displayed instead of the interface name in
the output of all show, show interfaces, and other operational mode commands.
Configuring an alias for a logical unit of an interface has no effect on how the interface
on the router or switch operates. To specify an interface alias, you can use the alias
statement at the [edit interfaces interface-name unit logical-unit-number] and [edit
logical-systems logical-system-name interfaces interface-name unit logical-unit-number]
hierarchy levels.
[See Interface Alias Name Overview.]
•
The request support information command (MX Series)—Starting in Junos OS Release
13.3, when you enter the request support information command with or without the
brief statement, the output includes the show system commit command output, which
displays the commit history and pending commits.
