Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands show vtp OL-8916-01 Table 2-30 show vtp counters Field Descriptions Field Summary advertisements received Subset advertisements received Description Number of summary advertisements received by this switch on its trunk ports. Summary advertisements contain the management domain name, the configuration revision number, the update timestamp and identity, the authentication checksum, and the number of subset advertisements to follow. Number of subset advertisements received by this switch on its trunk ports. Subset advertisements contain all the information for one or more VLANs. Request advertisements received Summary advertisements transmitted Subset advertisements transmitted Request advertisements transmitted Number of configuration revision errors Number of configuration digest errors Number of advertisement requests received by this switch on its trunk ports. Advertisement requests normally request information on all VLANs. They can also request information on a subset of VLANs. Number of summary advertisements sent by this switch on its trunk ports. Summary advertisements contain the management domain name, the configuration revision number, the update timestamp and identity, the authentication checksum, and the number of subset advertisements to follow. Number of subset advertisements sent by this switch on its trunk ports. Subset advertisements contain all the information for one or more VLANs. Number of advertisement requests sent by this switch on its trunk ports. Advertisement requests normally request information on all VLANs. They can also request information on a subset of VLANs. Number of revision errors. Whenever you define a new VLAN, delete an existing one, suspend or resume an existing VLAN, or modify the parameters on an existing VLAN, the configuration revision number of the switch increments. Revision errors increment whenever the switch receives an advertisement whose revision number matches the revision number of the switch, but the MD5 digest values do not match. This error means that the VTP password in the two switches is different or that the switches have different configurations. These errors means that the switch is filtering incoming advertisements, which causes the VTP database to become unsynchronized across the network. Number of MD5 digest errors. Digest errors increment whenever the MD5 digest in the summary packet and the MD5 digest of the received advertisement calculated by the switch do not match. This error usually means that the VTP password in the two switches is different. To solve this problem, make sure the VTP password on all switches is the same. These errors mean that the switch is filtering incoming advertisements, which causes the VTP database to become unsynchronized across the network.
