Guidelines for Applying Simple Filters
This topic covers the following information:
Statement Hierarchy for Applying Simple Filters
You can apply a simple filter to the IPv4 ingress traffic at a logical interface by including the simple-filter input simple-filter-name statement at the [edit interfaces interface-name unit unit-number family inet] hierarchy level.
[edit]
interfaces {interface-name {unit logical-unit-number {family inet {simple-filter {input filter-name;}}}}}
Restrictions for Applying Simple Filters
You can apply a simple filter to the ingress IPv4 traffic at a logical interface configured on the following hardware only:
- Gigabit Ethernet intelligent queuing (IQ2) PICs installed on M120, M320, or T Series routers.
- Enhanced Queuing Dense Port Concentrators (EQ DPCs) installed on MX Series routers and EX Series switches.
The following additional restrictions pertain to applying simple filters:
- Simple filters are not supported on Modular Port Concentrator (MPC) interfaces, including Enhanced Queuing MPC interfaces.
- Simple filters are not supported for interfaces in an aggregated-Ethernet bundle.
- You can apply simple filters to family inet traffic only. No other protocol family is supported.
- You can apply simple filters to ingress traffic only. Egress traffic is not supported.
- You can apply only a single simple filter to a supported logical interface. Input lists are not supported.
