Sorry, there is no equivalent OID for the vlan summary count.Currently we have only total and active subscriber summary counts in the Juniper Subscriber MIB.Besides this tunneled, terminated are L2 cross-connected counts are available per port.
Latest addition to subscribers MIB is shown below
-jnxSubscriberPicCountTable to provide per PIC subscriber count-jnxSubscriberSlotCountTable to provide per slot subscriber coun
Starting in Junos OS Release 16.1R1, you can monitor the total number of subscribers per PIC and per slot. The MIB tables jnxSubscriberPicCountTable and jnxSubscriberSlotCountTable are added to the Juniper Networks enterprise-specific Subscriber MIB to support this feature. In releases earlier than Junos OS Release 16.1, you need to use the show subscribers summary pic and show subscribers summary slot operational commands, respectively, to display the total number of subscribers per PIC and per slot.
Thanks Rahul for your kind help 🙂
