E120 and E320 System Maximums

Subscriber Management Maximums
Table 14 lists subscriber management maximums for the E120 router and the E320
router. The following notes are referred to in Table 14:
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.
On the E120 router, the SRP-120 and the SRP-320 support a maximum of 64,000
interfaces.
On the E320 router, the SRP-320 supports a maximum of 96,000 interfaces. The
SRP-100 supports a maximum of 64,000 interfaces.
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.
