ERX310, ERX7xx, and ERX14xx System Maximums

Link Layer Maximums
Table 3 lists link layer maximums for the ERX routers. The following notes are referred
to in Table 3:
1.
The ERX1440 router supports a maximum of 48,000 interface columns of all types
combined. You can use either all dynamic interfaces or a combination of dynamic
and static interfaces to achieve this maximum. For bridged Ethernet, IP network,
and PPP interfaces, the ERX1440 router supports a maximum of 32,000 static
major interfaces. Although the ERX1440 router supports a maximum of 48,000
static major interfaces for PPPoE, the PPPoE static limit is enforced at the
subinterface level, which has a limit of 32,000.
The ERX705, ERX710, and ERX1410 routers support a maximum of 32,000
interfaces of all types combined; the ERX310 router supports a maximum of
16,000 interfaces of all types combined. For these routers, the interfaces can be
any combination of dynamic or static.
The JunosE Software supports up to 10,000 PPP interfaces with EAP
authentication negotiation configured. Performance and scalability is unchanged
when EAP is not configured.
2.
The total maximum number of Ethernet subinterfaces that can be active at any
one time on an ERX310 router, an ERX7xx router, or an ERX14xx router is limited by
the number of slots per chassis. Of this total, you can configure all single-tagged
VLAN subinterfaces, all double-tagged S-VLAN subinterfaces, or a combination of
both VLAN subinterfaces and S-VLAN subinterfaces to achieve this maximum.
