ERX310, ERX7xx, and ERX14xx System Maximums

Appendix A: 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.
