You can change the default port mode (access or trunk). See the Cisco Nexus 1000V Installation and Upgrade Guide for information about setting the default port mode.

  • Page 31: High Availability

    • Do not connect devices with access links because access links may partition a VLAN. • When connecting Cisco switches through an 802.1Q trunk, make sure that the native VLAN for an 802.1Q trunk is the same on both ends of the trunk link.

  • Page 59: Vpc Host Mode

    You use vPC-HM mode to create a port channel when the switch is connected to multiple upstream switches that are not clustered. In the Cisco Nexus 1000V, the port channel is divided into subgroups or logical smaller port channels, each representing one or more uplinks to one upstream physical switch.

  • Page 60: Subgroup Creation

    Figure 5: Using vPC-HM to Connect a Port Channel to Multiple Upstream Switches Subgroup Creation If Cisco Discovery Protocol (CDP) is enabled on the upstream switches, subgroups are automatically created using information gathered from the CDP packets. If not, you must manually create subgroups.
