2. CORE: CAM, TCAM and SDM Templates
CAM




Content-Addressable memory ( CAM ) Stores [ Learner MAC address information]
MAC Addresses learned are Times Stamped; Renewed each Frame
MAC Addresses Moving Ports – Latest Time Stamp wins
Idle Cam Entries Are Kept for 300 seconds ( Default)
Key Commands:
- Show mad address-table ( or the older ‘ show mac-addresses-table;)
- Mac address-table static
- Mac address-table aging

TCAM
 Ternary CAM 0 TCAM) is a Layer 3 Version of the CAM Table
 Uses ASICS Combined with CAM memory to Accomplish Routing, ACLS and QOS via
HARDWARE
 Verify the TCAM Utilization with this command:
- Show Platform tcam utilisation

SDM Templates



Stakable Switched have Limited Resources That are Shared by CAM, TCAM, etc…
Verify your usage by using the ‘ show platform tcam utilization ’
Use ‘show sdm prefer ‘ to find out the usage template assigned
Use ‘ show sdm prefer ? ‘ to determine which template you should use

5. CORE: Handling Err-Disabled Ports



CAUTION: Err-Disabled ports are usually Disabled for Good Reason
Manual process: Shutdown/ no Shutdown
Automatic Process: Errdisable recovery cause / Errdisable Recovery Interval
Verification: Show Errdiasable Recovery
SHOW INT STATUS ERR-DISABLED

6. CORE: Managing Power over Ethernet
 Power Over Ethernet: Standards and UN-Standards
- Cisco Inline power ( 7W )
- 802.3AF (15.4W)
- 802.3AT ( 30W)
- Cisco Universal POE ( 60 W)
 Configuring POE on Cisco Switches

9. VLAN: All Things VTP

Page 6

KEY CONCEPTS:



VTP Domain Name / Password
Null Domain
VTP Pruning
ISL VLAN Limitation

 VTP VERSION 1
- The Classic !
 VTP VERSION 2
- Now With Token Ring Support
 VTP VERSION 3
- Complete rewrite
- No auto ( NULL )
- All VLAN Numbers Supported
- VTP Password Secured
- Primary Server concept Safety
- Private VLAN Support

VLAN: Trunking in Depth

 Trunking ( AKA TAGGGING ) Passes Multi-VLAn Information Between Switches
 Places VLAN information into each Frame
 Layer 2 Feature, can be negotiated ( not Recommended )
