Known Limitations in Juniper Cloud-Native Router Release 22.3

  • JCNR-2588: With Intel XL710 NIC if mid-haul bond link changes, traffic is not seen on VF–If the mid-haul link for the active link goes down, all traffic might be dropped on the new active link. Restart the jcnr-vrouter POD as a workaround.

  • JCNR-2607: After restart of vRouter or vRouter-agent, bond interface does not show in vif --list output–In some rare cases, if you restart either the vRouter-DPDK or vRouter-agent containers, the

    vRouter might not show the bond interface in the output of the vif --list command.

  • JCNR-2471: Stale interface entries found in vRouter even after deleting all JCNR-related Pods–In some rare cases, if you create and delete the same Pods multiple times old interface entries might appear in the output of the vif --list command.

  • JCNR-2276: MBUF memory pool leak–When packetgen pods are deleted and re-created repeatedly soon after traffic is applied, an mbuf mempool leak is observed.

  • JCNR-2205: L2 rate limiting does not work when configured for more than 1000000 Bps–If rate limiting is configured for more that 1000000 Bps, JCNR-vRouter will only rate limit at 1000000 Bps.

  • JCNR-2043: DPDK bond interface can fail to come up–If the physical interface (PF) link is down, a VF interface based on that PF interface does not come up.

  • JCNR-2400: Misleading License notification seen : LICENSE_TOKEN_REFRESH_FAILURE - License token refresh of feature 243 and quantity 1 has failed due to license deletion–This notification can appear when adding or deleting pods. It is safe to ignore this notification.

  • JCNR-2423: vRouter Pod crashes when traffic loop is present due to misconfiguration–The traffic loop causes continuous MAC move events between bond and switch interface.

  • JCNR-1413: All interfaces on host shown in cRPD–If you use the cRPD CLI and run a show interfaces command like show interfaces routing, the system displays all interfaces known to the host, even those that do not belong to Juniper Cloud-Native Router.
