Cisco Support in Tunisia After End of Life

The Same List, Two Different Sets of Packets

An access list applied to an interface acts on traffic in one direction: either entering the device through that interface or leaving through it. Those are different populations of packets. A list written correctly and applied in the wrong direction is still evaluated correctly — against traffic it was never intended to match, which means it permits exactly what it was written to stop.

Every Review Passes

The failure survives scrutiny because the scrutiny lands on the rules. The rules are right: the addresses, the ports, the ordering, the implicit deny at the end. The direction is a single keyword on a separate line that binds the list to an interface, often in a different part of the configuration, and it is not where an engineer checking policy logic naturally looks.

Silence reads as success

A filter that blocks nothing produces no logs, no drops and no complaints. In a security context that absence is easily read as the policy working, when it may equally mean the policy is not in the path. Tunisian estates carrying compliance obligations are exposed here in a specific way: the control exists, is documented and is demonstrably configured, and is not doing anything.

Match counters settle it

Every list keeps counters of what it matched. A list that should be active and shows none is not seeing the traffic, which points at placement rather than logic. That single reading distinguishes the two cases quickly and is worth making part of any change that touches filtering.

What ICD Supplies for Cisco Estates in Tunisia

Routing platforms, access and distribution switching, UCS nodes and fabric parts, optics matched to the cage and the distance to be covered, and power supplies rated for the module count the chassis now carries. The North Africa card places Tunisia at 2 to 4 days door-to-door from Cairo. Each module is exercised on the bench, tracked by its own serial, and backed one to three years.
