Hi Guys,Why is the switch reporting 2 different values for number of inbound packets that contain errors? snmpwalk still reports old error packet count after clearing counters.> snmpwalk -v2c -c SNMP_READ switch.cisco.com ifInErrors |grep 1055804IF-M...
I am not able to understand the following about BPDUGuard from Chapter 11 in "CCNP Self-Study: CCNP BCMSN Exam Certification Guide, Third Edition"-----Naturally, BPDU guard does not prevent a bridging loop from forming if an Ethernet hub is connected...
Hi guys,I am not able to capture all the traffic on a 6509 Router. It runs the followign software..IOS (tm) c6sup2_rp Software (c6sup2_rp-PK2SV-M), Version 12.1(23)E4, RELEASE SOFTWARE (fc1)The configuration changes that I made are..(all ip address a...
Hi,I have noticved that I cannot set port duplex to auto on a wsc6509 catalyst 8.3(4) Switch.> (enable) set port duplex 2/36 ? full Full duplex half Half duplexWill port duplex be in only 2 modes on all...
Hi,I have used ifIndex in IF-MIB and portType in CISCO-STACK-MIB to get the type of port on a switch.But is there a oid that can differentiate between Ethernet, Fast and Gig interfaces.Thanks,Prakash.
(config)# spanning-tree vlan 1-1024 root primaryI will have atmost 10-12 Vlans in some buildings. 2 reasons for doing that and using PVST.1) Since I have noticed BPDU traffic only for active vlans, I have enabled it for all vlans. I thought it will s...
I frequently use the words "spanning tree loops". The realization that only bridging loops occur is a stroke of enlightenment for me Thank you for response. I now feel comfortable about BPDUGuard and also about the implementation that I am planning...
Hi Mahmood,I have tested your scenario with a cross-over cable and BPDUGuard could detect the loop and error-disabled one of the port.So, the other example which I first mentioned is different where BPDUGuard will not detect the loop.I also envision ...
Hi Anand,Thank you for a detailed explanation of the scenario. I have assumed that HUB will receive BPDU Hello packets every 2 secs.Then when a new port is connected back to another upstream link, I assumed the new upstream link to hear BPDU hellos(o...
