ERX310, ERX7xx, and ERX14xx System Maximums

Subscriber Management Maximums
Table 7 lists subscriber management maximums for the ERX routers. The following
notes are referred to in Table 7:
1.
DHCP relay proxy maintains a list of active DHCP clients up to a maximum of
100,000 clients per chassis for all virtual routers. DHCP relay does not maintain a
list of DHCP clients.
DHCP relay proxy is notified of DHCP client deletions and subsequently deletes the
client’s host routes. In contrast, DHCP relay is not notified of DHCP client deletions,
so the host routes for deleted clients remain in DHCP relay until you permanently
delete them with the set dhcp relay discard-access-routes command. A maximum
of 100,000 host routes for DHCP clients can be stored for all DHCP relay and
DHCP relay proxy instances (that is, for all virtual routers).
2.
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.
3.
For DHCPv6 local server, up to 32,000 subscribers and clients are supported on
PPP/ATM and PPPoE/ATM with dynamic interfaces. Interface flapping tests have
been qualified for 8000 subscribers and interfaces.
