Changes in Default Behavior and Syntax

• Operational mode output change (J2320, J2350, J4350, and J6350 Services Routers)—Previously, the show chassis fpc command output for selected J-series Services Routers showed just the slot into which a 2-slot-high PIM was physically inserted. Now the output of the show chassis fpc, show chassis fpc slot, and show chassis fpc slot detail commands also indicate the slot that is unusable.
• Operational mode output change—The show chassis hardware and show chassis environment commands now show the status of redundant power supply modules in the J6300 and J6350 Services Routers. In addition, the output of the show chassis alarms and show system alarms commands now includes power-module-related alarms, if present.
• Setting a local loopback address—If you configure a local loopback address using the loopback statement at the [edit interfaces interface-name gigether-options] hierarchy level, the transmit path stops working, causing the remote end to detect a down link.
• New PIM abbreviation—In show chassis hardware command output for J-series Services Routers, the 2x CT1E1 identifier for the Dual-Port Channelized T1/E1/ISDN PRI PIM now appears as 2x CT1E1 / PRI to reflect the addition of ISDN PRI capability in the PIM.
• Increase in number of dialer pools—You can now configure up to 30 dialer pools on an ISDN PRI interface at the [edit interfaces interface-name dialer-options] hierarchy level. Previously the maximum was 16.
• Removal of an unsupported encapsulation type—Because flexible VLAN tagging is not supported on Fast Ethernet interfaces installed in J-series Services Routers, the flexible-vlan-tagging statement has been removed from the [edit interfaces fe-pim/0/port] hierarchy level in the CLI.
• Removal of unsupported source address filtering statement—The source-address-filter statement at the [edit interfaces interface-name gigether-options] hierarchy level has been deleted from the CLI, because J-series Gigabit Ethernet interfaces do not support MAC address filtering.
• Change in options hierarchy for serial interfaces—The control-leads statement at the [edit-interfaces se-pim/0/port] hierarchy level has been deprecated, and it is replaced by the dce-options statement. Serial interface functions and substatements remain unchanged. Although the control-leads statement still operates in existing configurations, use the dce-options statement for new configurations.
• MTU configurable on multilink dialer interfaces—You can now configure an MTU value on dialer interfaces with multilink encapsulation. To configure this setting, include the mtu statement at the [edit interfaces dl0 unit logical-unit-number family inet] hierarchy level.
