Is there a command to view maximum number of MAC address entries in CAM table in Catalyst series switches? I have usually found this information from release notes.
Yes, but this might be platform dependent.
For example, on Cisco 4900M:
4900M#show mac address-table count MAC Entries for all vlans: Dynamic Unicast Address Count: 8507 Static Unicast Address (User-defined) Count: 130 Static Unicast Address (System-defined) Count: 18 Total Unicast MAC Addresses In Use: 8655 Total Unicast MAC Addresses Available: 55000 Multicast MAC Address Count: 28 Total Multicast MAC Addresses Available: 32768
3560#show mac address-table count Mac Entries for Vlan 738: --------------------------- Dynamic Address Count : 1 Static Address Count : 0 Total Mac Addresses : 1 [...] Total Mac Address Space Available: 5894
