Hello! I've typed show running-config interface GigabitEthernet 9.500 and show running-config interface GigabitEthernet 1/0/1 in the CLI respectively. At the same time of typing those commands I've captured the TACACS+ accounting packets with Wireshark. The packets are containing the following data:
"Group-Async 1 GigabitEthernet 1 0 1" - is not GigabitEthernet1/0/1 at all. So I do worry about it, because it is not internal formatting only, but sent to accounting log as well. For example, NX-OS does not do that. If it is "Ethernet1/1" in the CLI command, then it is "Ethernet1/1" in the accounting log. Catalyst 3650 does replace slashes only, Catalyst 2960X does do both of things.
