We recommend the following hold times for each protocol, based on the number of interfaces. Recommended Hold Time for OSPF 80 seconds 87 seconds 90 seconds Interface Count 16000 or less 16001 to 32000 32001 to 48000 Recommended Hold Time for IS-IS 50 seconds 55 seconds 70 seconds 32 Known Behavior Release 10. 3. 2 When IP tunnels are configured on a router enabled for stateful SRP switchover, and the Service Module (SM) carrying these tunnels is reloaded, stateful SRP switchover transitions to the pending state. Stateful SRP switchover remains in the pending state for 10 minutes following the successful reloading of the SM. This amount of time allows for IP tunnel relocation and for the tunnels to become operational again on the SM. If an SRP switchover occurs while in the pending state, the router performs a cold restart. Work-around: None. Subscriber Interfaces MAC address validation is not supported on either of the following: Packet-triggered subscriber interfaces that are created dynamically Packet-triggered subscriber interfaces that are managed on the primary IP interface A packet-triggered subscriber interface is created when the router receives a packet with an IP source address that does not match any entries in the demultiplexer table. When the router detects an unmatched packet, it generates a trigger event that determines whether to create a dynamic subscriber interface or configure an existing interface. To configure packet detection on the router, use the ip auto-detect ip-subscriber command. System ERX routers display different behavior from E120 routers and E320 routers when reporting modules as inactive. ERX routers report a module as inactive when either: The I/O module is not present The primary line module is fully booted and ready to resume operation. E120 routers and E320 routers report a module as inactive when either: The primary line module has no IOAs. The standby line module has taken over for the primary line module, and has control of the IOAs. Because E120 and E320 routers can accommodate up to two IOAs per slot, at least one IOA must be online. If the second IOA fails, the line module is still online, but does not use both IOAs. You can ensure that every module is up and active in the system and not in a failed state by issuing the show version all command. Known Behavior 33 JunosE 10. 3. 2 Release Notes In a router with a redundancy group that does not span quadrants (for example, a three-slot redundancy group that spans slots 0, 1, and 2 in an ERX1410 chassis), the potential bandwidth of the redundant module is erroneously included in the quadrant bandwidth calculation. The show utilization command might indicate that the bandwidth is exceeded for modules in that group. [Defect ID 31034] When you copy the running configuration to NVS, the E Series router verifies whether it has available space equal to at least twice the size of the . cnf file. [Defect ID 40655] Work-around: Make sufficient space on the NVS by deleting . rel or . cnf files. You cannot delete the ipInterface log after you delete the corresponding IP interface. This does not prevent you from adding filters to other interfaces, nor does it prevent you from adding a filter to the same interface if you re-create it after deletion. [Defect ID 34842/45063] Work-around: Remove the filter before you remove the interface. Alternatively, if you remove the interface first, then you must remove all filters associated with all IP interfaces. System Logging If you enable engineering logs and set the control network logs to a level of notice or lower (down from the default of error), you might see erroneous controlNetwork log messages like the following that are generated because SNMP polling on line modules (correctly) detects no fabric: [Defect ID 43168] NOTICE 09/01/2002 18:47:52 CEST controlNetwork (slot 11): Control Bus Master slave error 0x5 while accessing slot Tunneling When you configure the GE-2 line module, the GE-HDE line module, or the ES2-S1 GE-4 IOA to operate as a shared tunnel-server module, the available bandwidth for tunnel services is limited to 0. 5 Gbps per module. In releases numbered lower than Release 7. 3. 0, a dynamic tunnel-server port was located on port 8 of the GE-HDE line module and GE-8 I/O module. [. . . ] These values are subject to limitations on available SRP module memory, which varies according to your router configuration. Depending on your configuration, the router may support more routing table entries or fewer routing table entries than this value. In any case, you can choose to limit the number of routes that can be added to the routing table on a per-VR or per-VRF basis by means of the maximum routes command. The maximum number of ANCP adjacencies can be scaled over a maximum of 100 virtual routers. [. . . ]
