Parameter
Description
Valid Options
MAC Forced-Fwd
(VDSL2 and PON only) Whether to enable MAC Forced Forwarding
(MAC FF) which screens upstream packets at the ONT Ethernet port or
xDSL port and only allows through those packets with a destination
MAC address (DMAC) that matches the upstream access router. Calix
recommends MAC Forced Forwarding be enabled for all residential and
business internet access services. MAC FF supports the following:
IP hosts learned via DHCP Snooping
IP hosts statically provisioned (IP and MAC)
IP hosts statically provisioned (IP address only)
IP subnets statically provisioned (single IP address/MAC)
Note:
Maximum number of service VLANs with MAC Fored-Forwarding
and/or IP-Source-Verify enabled, per VDSL2 line card = 48.
cleared (disabled) ‡
selected (enabled)
IP Src Verify
(VDSL2 and PON only) Whether to bind the IP address and MAC
address to the physical ONT Ethernet port or xDSL port, preventing
subscribers from assigning an IP address to a device and passing traffic
on it. IP Source Verification for Static IP hosts requires MAC FF be
enabled. Calix recommends IP Source Verification be enabled for all
residential and business internet access services.
Note:
Maximum number of service VLANs with MAC Fored-Forwarding
and/or IP-Source-Verify enabled, per VDSL2 line card = 48.
cleared (disabled) ‡
selected (enabled)
MAC Learning
Controls MAC address learning. This parameter control only applies to
standalone E7-2 systems.
E7-20 and E7-2 in Modular Chassis mode only support MAC
Learning
enabled
.
E7-2 system cannot be set to Modular-Chassis mode while any
VLAN has MAC Learning disabled.
Calix recommends leaving MAC Learning in the default enabled mode.
Disabling MAC learning causes traffic within the VLAN to be flooded
to all egress interfaces with membership in the VLAN.
Disabling MAC Learning and DHCP Snooping, and enabling MAC
Forced-Fwd, causes all downstream packets to be flooded.
Enabling DHCP Snoop, sets MAC Learning to disabled by default.
cleared (disabled)
selected (enabled) ‡
AE Discovery Event
Whether the E7 sends an event to CMS whenever a new Calix AE ONT
is discovered on an untrusted port. When enabled, an event is sent for
any new lease added to the binding table entries belonging to AE
ONTs. If the lease for the AE ONT already existed in the table at the
time of enabling the feature, an event will not be sent.
Note:
DHCP Snoop must be enabled on the VLAN to support the AE
Discovery Event operation.
cleared (disabled) ‡
selected (enabled)
TLAN
(VDSL2 and PON only) Whether to enable PON or xDSL transparent
LAN service which disables Ethernet Security Profiles, MAC Forced
Forwarding, DHCP Lease Limits, or Upstream Broadcast Limits that
were applied to the ONT Ethernet port or xDSL port with the associated
VLAN.
Note:
The default behavior for data services is to limit multicast traffic
upstream from an ONT Ethernet port or xDSL port, unless the TLAN
parameter is enabled on the VLAN. For GPON or xDSL VLANs that
need to carry IPv6 traffic, enable the VLAN TLAN parameter for
transparent passthrough of IPv6 traffic.
cleared (disabled) ‡
selected (enabled)
PON Hairpin
(PON only) Whether to enable PON hairpin which allows traffic to flow
upstream from an ONT Ethernet port and back downstream on the
same PON to another ONT Ethernet port. The PON Hairpin function is
not compatible with DHCP Snoop, IGMP snoop, MAC Forced-Fwd, or
IP Source Verify.
Note:
Supported for TLAN and T1/E3 PWE3 services.
cleared (disabled) ‡
selected (enabled)
