I've found this link: http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/release/notes/overview.html#wpxref22992
with this note I'm not sure about: "In Release 12.2(33)SXI1 and later releases, these limits do not apply to WS-X67xx and WS-X65xx switching modules. (CSCsu30263)" I'm also wondering about mac-address-table sincronization issue... http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-series-switches/71079-arp-cam-tableissues.html#dfc Do anybody have an idea/experience ? Tks From: [email protected] To: [email protected] Subject: C6500 issue Date: Fri, 13 Dec 2013 13:23:43 +0000 Hi I run on C6500 (SUP720) IOS 12.2(33)SXI5 and sometimes I got sporadic problems on production systems that I find really difficult troubleshoot. The only thing I found strange is the following amount of STP active ports: #sh spanning-tree summary totals Switch is in rapid-pvst mode Root bridge for: xxx EtherChannel misconfig guard is enabled Extended system ID is enabled Portfast Default is disabled Portfast Edge BPDU Guard Default is enabled Portfast Edge BPDU Filter Default is disabled Loopguard Default is disabled Platform PVST Simulation is enabled PVST Simulation Default is enabled but inactive in rapid-pvst mode Bridge Assurance is enabled UplinkFast is disabled BackboneFast is disabled Pathcost method used is short Name Blocking Listening Learning Forwarding STP Active ---------------------- -------- --------- -------- ---------- ---------- 424 vlans 228 0 0 4037 4265 I see these number of virtual ports: #sh vlan virtual-port Slot 1 ------- Total slot virtual ports 1954 Slot 2 ------- Total slot virtual ports 1944 Slot 3 ------- Total slot virtual ports 262 Slot 4 ------- Total slot virtual ports 398 Slot 5 ------- Total slot virtual ports 423 Slot 6 ------- Total slot virtual ports 423 Slot 7 ------- Total slot virtual ports 372 Slot 8 ------- Total slot virtual ports 74 Slot 9 ------- Total slot virtual ports 148 Total chassis virtual ports 5998 On slot 1 and 2 I run WS-X6708-10GE. My questions: 1) Why there is a difference in the total of STP active ports (4265) and vlan virtual port (5998) ? 2) Do you see any overcoming limits in these number ? to me total seems ok, I’m wondering if per slot or per port we overcome the limits 3) could be this issue the root cause of the problem ?
