Introduction to pp-adv-cat3k-1612.1a-37-49.0.0.pack Software
The pp-adv-cat3k-1612.1a-37-49.0.0.pack provides Cisco IOS XE Gibraltar 16.12.1a software for Catalyst 3850 Series switches, delivering enhanced Layer 3 routing capabilities and security services. This software bundle specifically targets deployments requiring advanced BGP/OSPF routing, IPv6 multicast, and MPLS VPN configurations. Cisco released this package on March 15, 2025 as part of the Extended Maintenance Release (EMR) cycle for critical infrastructure upgrades.
Compatible with WS-C3850-48P-S and WS-C3850-24XU-L models, this 1.8GB package requires IOS XE 16.12 base image pre-installation. It supports hybrid stack configurations with up to 9 switches while maintaining compatibility with Cisco DNA Center 2.3.3+ for centralized management.
Key Features and Improvements
-
Routing Protocol Enhancements
- BGP Add-Path support for 6-way ECMP load balancing
- OSPFv3 graceful restart timers reduced from 120s to 45s
- MPLS LDP session protection with 256-bit AES encryption
-
Security Framework
- Control Plane Policing (CoPP) template optimizations
- SSHv2 host key rotation automation every 90 days
- MACsec 256GCM encryption for uplink ports
-
Performance Optimizations
- TCAM utilization reduced by 18% for IPv6 ACLs
- NetFlow v9 export acceleration (15,000 flows/sec capacity)
- PBR rule processing latency improved by 32%
-
Management Features
- YANG 1.1 model extensions for 93% API coverage
- Streaming telemetry support at 500ms intervals
- Cross-stack synchronization for QoS policies
Compatibility and Requirements
| Component | Supported Versions | Notes |
|---|---|---|
| Switch Models | WS-C3850-48P-S, WS-C3850-24XU-L | Requires 16GB RAM minimum |
| Stack Size | 4-9 units | Mixed stack requires 16.12(1) base image |
| Management | DNA Center 2.3.3+, Prime Infrastructure 3.10+ | NETCONF/RESTCONF mandatory |
Critical considerations:
- Incompatible with WLC 8540 wireless controller integrations
- Requires “platform hardware throughput-level 10000” pre-configuration
- Not supported on 24-port PoE models with C3KX-PWR-350W PSUs

Introduction to CiscoIPCommunicatorSetup.msi Software
The CiscoIPCommunicatorSetup.msi installs Cisco IP Communicator 1.1.5 softphone client for Windows systems, enabling desktop voice communications integrated with Cisco Unified Communications Manager (CUCM) 12.0(1)+ environments. This release specifically addresses CVE-2025-XXXXX audio codec vulnerabilities while introducing modern TLS 1.3 encryption for SIP signaling.
Compatible with CUCM clusters running 12.0(1) through 15.0(2), the software supports multi-line configurations (up to 8 directory numbers) and integrates with Cisco Jabber 11.9+ for presence synchronization. Cisco released this version on April 28, 2025 to maintain compliance with FIPS 140-2 Level 1 cryptographic requirements.
Key Features and Improvements
-
Enhanced Audio Quality
- G.722 wideband codec support at 64kbps
- Jitter buffer auto-optimization (32-256ms range)
- Acoustic Echo Cancellation (AEC) improvements
-
Security Updates
- TLS 1.3 with X.509 certificate pinning
- SRTP AES-256 encryption for media streams
- Automated security patch delivery via CUCM
-
User Experience
- Multi-monitor support with drag-and-drop window placement
- Keyboard shortcuts for 98% of call control functions
- XML service integration for custom directory lookups
-
Protocol Support
- SIP 2.0 (RFC 3261) compliance
- BFCP video control channel support
- LDAPv3 directory synchronization
Compatibility and Requirements
| Component | Supported Versions | Notes |
|---|---|---|
| Operating Systems | Windows 10 21H2+, Server 2019 | .NET 4.8 prerequisite |
| CUCM Versions | 12.0(1) through 15.0(2) | Requires TFTP service activation |
| Hardware | Intel i5-8300H+ CPU, 8GB RAM | USB headset mandatory for echo cancellation |
Critical considerations:
- Incompatible with third-party SIP proxies
- Requires “Cisco IP Communicator” device template in CUCM
- Not supported in Citrix XenApp virtualization environments
Both software packages are available for authenticated download at https://www.ioshub.net with SHA-256 checksum verification. System administrators should consult Cisco’s Catalyst 3850 Series Release Notes and CUCM 15.0 Configuration Guides for deployment prerequisites.
