jnxJsScreenMonIpv6ExtLimit
Module: JUNIPER-JS-SCREENING-MIB
OID (symbolic): JUNIPER-JS-SCREENING-MIB::jnxJsScreenMonIpv6ExtLimit
OID (numeric): 1.3.6.1.4.1.2636.3.39.1.8.1.1.1.1.45
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: In one IPv6 packet, one or more extension headers may appear before the encapsulated payload. User can screen IPv6 packets if their extension header number is larger than one limit.
When the extension header limit screen is enabled, the device screens IPv6 packets with more than one limit extension headers.
The attribute counts the number of block IPv6 packets.
What is jnxJsScreenMonIpv6ExtLimit?
This read-only counter tallies IPv6 packets blocked in this zone for carrying more extension headers than the configured limit (jnxJsScreenIpv6ExtNumLim), a heuristic against extension-header-stuffing evasion techniques. An admin watching this counter climb confirms the extension-header-count screen is actively filtering excessive header chains.
