HP 2520-8 Configuration Manual page 47

Outbound Telnet establishes a Telnet session from the switch
CLI to another IPv6 device, and includes these options.
• Telnet for Link-Local Addresses on the same VLAN requires
the link-local address and and interface scope:
< link-local-addr >: Specifies the link-local IPv6 address of
the destination device.
%vlan< vid >: Suffix specifying the interface on which the
destination device is located. No spaces are allowed in the
suffix.
• Telnet for Global Unicast Addresses requires a global unicast
address for the destination. Also, the switch must be
receiving router advertisements from an IPv6 gateway
router.
< global-unicast-addr >: Specifies the global IPv6 address of
the destination device.
For switches that have a separate out-of-band management
port, the oobm parameter specifies that the Telnet traffic will
go out from the out-of-band management interface. If this
parameter is not specified, the Telnet traffic goes out from the
data interface. The oobm parameter is not available on
switches that do not have a separate out-of-band management
port. Refer to Appendix I, "Network Out-of-Band Management"
in the Management and Configuration Guide for more
information on out-of-band management.
For example, to Telnet to another IPv6 device having a link-local address of
fe80::215:60ff:fe79:8980 and on the same VLAN interface (VLAN 10), you
would use the following command:
Switch(config)# telnet fe80::215:60ff:fe79:980%vlan10
If the switch is receiving router advertisements from an IPv6 default gateway
router, you can Telnet to a device on the same VLAN or another VLAN or
subnet by using its global unicast address. For example, to Telnet to a device
having an IPv6 global unicast address of 2001:db8::215:60ff:fe79:980, you
would enter the following command:
Switch(config)# telnet 2001:db8::215:60ff:fe79:980
