| Parameter | Limit | |-----------|-------| | MAC addresses | 12,000 | | IPv4 routes | 11,000 (hardware) / 16,000 (software) | | IPv6 routes | 4,000 | | Access list entries (ACE) | 2,000 | | VLANs | 1,000 (1–4094, minus reserved) | | Switched bandwidth | 32 Gbps backplane | | Routing throughput | ~8 Mbps (CPU-limited) – Do not route inter-VLAN at wire speed | Cisco IOS filenames are not random; they follow
Critical performance note: The 3560 routes in software (CPU), not hardware (ASIC). Inter-VLAN routing with ACLs will saturate the CPU at ~10–15 Mbps. For routing, use a real router or 3560E/3750E. Real-world limits for this image on a 3560-48PS:
Cisco declared End of Software Maintenance for 15.0(2)SE on Nov 30, 2021. No further security fixes exist.
While the IP Base image supports static routing and basic RIP, the IP Services image unlocks the heavy hitters:
